Does ANYONE know about this type of Antenna or perhaps owns one of these. I was very interested in buying one of these and was wondering if someone could buy one and where. They are very close to Sirio in looks and perhaps performance. I do happen to have a Sirio S-827 and it is a GREAT and tough made 5/8 wave Antenna. But I would very much like to have more information on this Antenna both pros and cons. Sigma Antenne of Italy has a full line of Antennas and some of the beams seem to be made like the Jo Gunn booms that are squared off type in appearance. It would be interesting to see if there is a distributer that sells these here in the USA..
Thanks

Dnt777,

Yes I have one I have been using/testing the SIGMA MANTOVA TURBO
BASE STATION ANTENNA

&
using and testing the
SIGMA DIRETTIVA 3 ELEMENTI
BASE STATION ANTENNA
since April 13th, 2007 and doing a Copper Forum Review on BOTH of them.



MANUFACTURER SPECIFICATIONS:

* Frequency 26-28 mhz,
* 50 ohm,
* Maximum power 2000 w
* Vertical polarization,
* Weight 4,5 kg,
* Height approximately 23'-8"
* 8 ~ 5' long Radials
that mount to 4" Radial Hub of bottom section.
* SO238 Coax Connector with connector cover.
* RELATIVE GAIN: 8 dB

More information will follow when my Copper Forum Review is finished.

But I can say the SIGMA MANTOVA TURBO BASE STATION ANTENNA's performance is EXCELLENT! on 10/11 and 12 Meter's with NO tuning or antenna tuners needed.

And the SIGMA DIRETTIVA 3 ELEMENTI BASE STATION ANTENNA
is also performinmg EXCELLENT


MANUFACTURER SPECIFICATIONS:

* Frequency 27mhz ~ other's with tuner
* 50 ohm,
* Polarization: Vertical or Horizontal
* Maximum power 1000 W
* Elements: 3
* SO239 Coax Connector with connector cover.
* Relative Gain 8dbi
* Weight: About 8.8 lbs
* Director: About 17.25'
* Center Element: About 18.1'
* Reflector: About 18.8'
* Boom: About 9.3'
* RELATIVE GAIN: 8 dB

And so far BOTH Antennas have withstood 3+ inches of ICE on them and 70+ mph winds during the Ice/Snow storm with NO bent or broken elements.

Do you Climb your tower,
Every time you want to talk on 26,27,28,or 29 mhz.
to adjust the s.w.r.s OR Use a Tuner ?

Johhn,

Sorry but no I do not have to climb my tower to make any adjustments on the SIGMA MANTOVA TURBO BASE STATION ANTENNA.

If I want to talk on 10/11/12 meters all I do is simply change the band switch on my radio's to 10/11 or 12 meters and start talking.

NO Antenna Tuner & NO Adjusting for SWR.

It makes it VERY NICE for the Sunday CEF Radio Club 10/11/12 Meter Nets.

Johhn,

The SIGMA DIRETTIVA 3 ELEMENTI BASE STATION ANTENNA is an aluminum antenna.

As the Reviews by myself and several other Copper Forum Member's on several of the SIGMA Antennas are still in progress the Sigma Antennas will not be listed on the Copper web site until the Reviews are finished and the antennas are in stock and ready to be shipped.

An Announcement and the Review's will be posted in the Copper Forum when they are available.

Johhn,

Sorry but I have no idea what is on the internet but as I posted above in this Topic I personally have found NO reason to use an antenna tuner for full coverage of the 10/11/12 meter bands with SWR Readings of:

CB/11 Meter Band:
CB Channel #1 ~ SWR-1.4
CB Channel #13 ~ SWR-1.3
CB Channel #40 ~ SWR-1.0

10 Meter Ham Band:
28.000 ~ SWR-1.1
29.700 ~ SWR-1.5

Note!

While this antenna was not advertised/rated for the 12 Meter Ham Band from the factory, I have been using it on the 12 Meter Ham Band with excellent results/feedback.

12 Meter Ham Band:
24.890 ~ SWR-2.0
24.990 ~ SWR-2.5

Johhn,

The SIGMA MANTOVA TURBO
BASE STATION ANTENNA


This means the Coil, Antenna above the Coil, Antenna below the Coil and the 8 Radial Elements are all aluminum.

Hope this helps to explain it.

All further/additional information will be included in my Review when it is posted.

Yes My V-5/8's is at 2.8 at 29.350, so this is why I use a tuner ,I see my wattage drop off.
The CPU sees the high reading.

Tech 808 can you tell me what they use as a reference point in claiming 8 db gain? I have never see a vertical mono band antenna that has this much gain.The fundamental comparison antenna is the isotropic radiator which has 0 gain and the half wave dipole has 2.1 gain over the isotropic,so a 5/8 wave antenna should have about 3 to 4 db gain over isotropic which in the real world would be more like 2 to 3 db gain over lets say a 1/4 way ground plane as a reference.There is no way that a vertical will have the same gain as a 3 element yagi,sounds a bit like the A99 at 9.9 dbi which is not possible in the real world
Bob VE1CZ/CEF451

Moderator Note!

Sorry but I honestly have no idea what SIGMA uses as a reference point in claiming: RELATIVE GAIN 8 dB

Tech 808.
Could you tell me where I could purchase a Sigma Mantova Turbo? Has there been any more word if Copper can sell these or maybe special order one?
I know these are sold in the European market but I believe that this is a really GREAT product. And I believe that the quality of this product would really be a fine asset to both the Amatuer and the CB world. If your testing and your results are satisfactory, then this really should go on the American Market without any delay. Can you give me any more thoughts on this matter.
Thanks

Hello 808,The question that captain radio posted is a very good one indeed ! How did you come up with those gain figures ? I believe he and I were taught antenna theory the same, and I cannot possibly realise this type of gain that you have come up with. I believe a reasonble explanation is due since alot of us are very interested in this antenna when it becomes available to the public for sale. Thanks

Moderator Note!

The manfacturer specifications state:
RELATIVE GAIN: 8dB

So 808, next month will be the 1-year anniversary of testing the Sigma Turbo Omni & the 3 Elem Beam, right? Really looking forward to data on how that Turbo has fared thus far. On paper, looks like it might give my Imax a run for its money...or better? I still have a soft spot for high gain Alum. antennas since owning a RS Archer in '83 that was incredible talking dx barefoot. 3 questions- when will you post full reviews, can you share any early data and when will they be available at Copper (or otherwise in the US)? Thanks!

Canal_digger,

So far the SIGMA MANTOVA TURBO
BASE STATION ANTENNA

and

SIGMA DIRETTIVA 3 ELEMENTI
BASE STATION ANTENNA

have BOTH outperformed any Omni antenna or 3 Element Beams that I have ever used on BOTH TRANSMIT and RECEIVE.

As the Forummaster is working on the deal with Sigma all information will be included in the Reviews.

Iam just guessing that it will be 3 or 4 months before they are in stock and ready to be shipped.

Until the deal is complete and the antennas are shipped and in stock no price can be set.

It is impossible to try and figure/guess the cost of shipping depending on amount of antennas / models ordered, size and the total weight of an order along with import taxes on items that have not been purchased/ordered/shipped.

When the SIGMA Line of Antennas are IN STOCK and ready to be ordered/shipped all prices will be posted on the Copper Web Site for the SIGMA line of antennas.

If so, do the elements pass directly through the boom?

Jim,

Yes the Boom on the SIGMA DIRETTIVA 3 & 4 ELEMENTI BASE STATION ANTENNA's is Square.

Check out the picture I posted in the 2nd post in this Topic above.

The elements mount FLAT on top of the Square/Boxed boom.

Which gives them more strength than elements that pass throuh a boom.

And eliminating the possibility of the elements wallowing up & down and cutting into the element’s like with antennas that have elements that pass through the boom.

So far ours has withstood 80+ MPH winds and 3" of ice hanging from the elements and NO sagging of element’s and NO bent or broken elements.

SM Turbo or Imax2K at same height, same radio, etc.? To put it another way, should I start saving about $20/week now to upgrade from my Imax when Copper gets them?

Lon, do you have the test beam mounted HORZ or VERT? I'm guessing HORZ mounted. That would give you less windload to worry about, but, a real test for ice accumlating on elements.
I think you said, others are testing this beam.
Anyone testing it mounted vert. in a windy area?

Moderator Note!

Jim,

I am testing the SIGMA DIRETTIVA 3 ELEMENT BEAM in the Horizontal mode as I already have the SIGMA Mantova Turbo for Verticle use.

By testing it in the HORIZ Mode allowed me to see how it performed in the wind and with Ice build up on it and see if any of the elements would bend or break.

Sorry but no others are testing the SIGMA MANTOVA TURBO or SIGMA DIRETTIVA 3 ELEMENT BEAM but other Copper Forum Member's are Testing other SIGMA Models for Copper Electronics.

WITH EXCELLENT Results and Reports. .

We do have others testing other models of the SIGMA line of Antennas and EVERYONE has been VERY PLEASED with the performance.

Yes start saving.

It has been tested in side by side actual on air testing daily and during the Sunday CEF Radio Club Net's at 36' against our IMAX 2000 w/GPK, Anttron 305 and Maco V/58 and it has out performed all 3 of them on TX & RX.

Lon, boom length 9' 3" long on 3 element beam. I'm taking it that the boom assembles together using 2-3 separate pieces. Does the boom appear solid? How does the boom mount together? Does it use standard hardware or Stainless hardware?
Most beams use standard hardware, but, I thought i'd ask. Thanks!

Jim,

Sorry had DR and running to do today.


ASSEMBLY:

Very straight forward / easy and takes less than 10 minutes by yourself.

Holes are pre-drilled for mounting element's on square boom and for assembling element's.

NO sliding element's in and out to adjust for low SWR on 27mhz like on other beams.

Simple single peice Aluminium rod Gamma Match w/so-239 connector that accepts a standard PL-259 that mounts directly to the boom and a single alumunium block that slides over the center element and gamma match for adjusting SWR (which I did not need to adjust from the assembly instructions.)

2 piece Boom is VERY STRONG/STURDY as if you look at the picture I posted above the main joint is in the middle of the HEAVY DUTY boom bracket.

Stainless nuts/bolts.

Well I guess if I was unable to BEG, BORROW, STEAL or TRADE Uncle Hal for a SIGMA MANTOVA TURBO I would be forced to use/choose the IMAX2000 w/GPK kit as a last resort.

IMAX2000 w/GPK kit and bend the ears up for the GP radials on the bracket bent to 30° as suggested / recommended by: Paul ~ Tech833

I was also wondering about the statis of this antenna. It is now, June the 7th and was just wondering if there is any word about if Copper is going to get these soon in for shipment. I still would very much like to get one of these. Please let us know. I still believe that this is one of the BEST ground planes around. As an Amateur operator I believe that it would cover a lot of other bands with tuner with great results. Thanks...

In checking availability of this antenna, only Europe at this time stocks it (Italy, Germany, France). No one in England or Canada that I can find. Just Shipping alone is in Euro dollars and about 160-190, which is anywhere from US $250-300. So, let's hope Copper can get some leverage and get these over here in a bulk order! I'm in if they want to do a "Pre-order".

When is Copper going to get the SIGMA MANTOVA TURBO BASE STATION ANTENNA??? And the Beam? It seems like a very long time to get them in. I wonder if these antennas are real or just a myth. Like so many other things you hear on the radio.

Thanks for looking into that, Lon. If available this summer/fall, I'd like to replace my Imax 2000 and get it up before the winter. Not that the IMax isn't doing OK, but in everything I've read thus far, sounds like there is a measurable difference in tx/rec between them. Can you share the actual tests you mentioned you preformed (CEF Radio Club) in your March 14th comment in the mean time? Would love to see what you found.

Tech 808: What is now the statis of the Sigma Mantova Turbo? I read your review of the favorite omni antennas and you stated that it was the Turbo and the 3 element beam.
But the question is, When and where can one GET the Turbo. Has Copper made any deals to get any? Really curious and been waiting a LONG time on this one. Can you enlighten all of the Copper Customers of these Antenna Products. Please. .

.Well after 3 days of ICE now and MORE ICE coming through tonight and tomorrow and about 1" to 1-1/2" of ice on them now, they are still up and the #3-elements on the beam's and #8 - 4' elements on the omni are NOT bent or broken.

My #1 choice for an OMNI Antenna is the: SIGMA MANTOVA TURBO.

My #1 choice for a BEAM Antenna is the:
SIGMA DIRETTIVA 3 ELEMENT BEAM.

OK, it's my B-day soon, so I figure you can at least share the field test data on both the Mantova Turbo Omni and the 3 Element Beam? That would give all of us the time to compare and (probably) prepare to purchase one of these later this year? Anything technical would be good at this time. Thanks!

Canel_digger,

Give me until Saturday and I will re-test both antennas and post the results.

All of the technical information on the SIGMA MANTOVA TURBO BASE STATION ANTENNA is posted above in this topic.

ok guys,

for all of you that have been asking about it and not getting a straight answer; the DB gain of the vertical that lon is testing is about 2.5dbi.
that means it has no real world gain at all.
(this gain figure was reached by having a broadcast engineer friend look at the patent sheet for the antenna)

it is simply another vertical antenna that happens to cover more freqs with a lower SWR than others.

if you want an antenna that you can talk on 12/11/10 meters with, without using a tuner, then this will be a good antenna for you.

if you already have a V5/8 wave maco, or an IMAX2000, then you already have a superior antenna to this sigma antenna. IMO

the "8 db" gain figure in the ad is misleading.
notice that when they give the gain figure for the 3 element beam antenna directly below it, that they use the term "dbi" which means db gain over isotropic, which is a theoretical antenna used for reference purposes. this theoretical antenna has a 2.15 db advantage over a real world dipole antenna when used as a reference, so anytime you see the "dbi" reference used, you need to subtract 2.15 db from their claim to get the real world advantage of the antenna over a dipole.

read the ads in ham magazines, they will use the "dbd" (db gain over dipole)reference because they know that hams know better than to believe arbitrary antenna claims made by the manufacturer.

the 3 element beam claims 8dbi gain, which really means that this antenna will have a 5.85 db gain over a half wave dipole antenna.

lets get Tech833 in on this discussion, and have him explain how this vertical antenna achieves its magical "8db" gain figure.

in the end, we will all find that this "new" vertical antenna is the same as all the others out there, just a bit more broadbanded.

have fun,
KV
anyone wanting a "clean signal", just look to the left and build one of these!!!

Just the facts .....

There IS NO WAY to get gain other than to compress the 360 by 360 deg to get a REAL 8 DB gain along the horizon you have to compress the vertical lobe down to 12 deg..... think of it as the earth and you just put your hand on the north and south poles and FLATTENED the world so only the equator showed. On VHF/UHF they do just this by STACKING antennas one on top of each other on bands like 440 MHz with 8 antennas stacked on top of each other gains of 9 DB are not uncommon.

A great way to get more gain is to have an antenna set up in a collinear fashion which is more or less phasing multiple antennas of the same type.You see this quite often on the vhf and uhf bands using folded dipole antennas. As far as the sigma vert. having 8 db seems very hard to believe and also an antenna made for one band that covers 3 or more bands with low swr is most likely not that efficient, hey a 50 ohm dummy load will show great swr almost any where.

at not much more then 22' to the feed point, my 22+ year old maco v5/8 outperforms a friends sirio 2016 5/8 wave AND a mr coily enforcer. receive, xmit, local, skip. we are equal distance from the water, and the other 2 antennas have mine in height by 15' and 20+ feet. current & past comparisons to base antennas with that
$%&#@ coil have shown that the maco beats all of THEM. my guess is it will do the same to the mantova. i'm sticking with my 22+ year old maco v5/8, and just in case, i have another one, new in box. as for the beam, 3 elements, 6db gain, more or less, yup, that's typical.
as for the mantova....lets get Tech833 in on this discussion, and have him explain how this vertical antenna achieves its magical "8db" gain figure, i agree, matt.

Sorry, but I only posted the Ralative Gain from the Manufacturer Specification's listed on the SIGMA website.

Now with that said after testing it in real world side by side testing against an IMAX 2000 with GPK kit and the "GPK kit bent to 30° per Tech833's recommendation, and MACO V5/8 the Sigma Mantova Turbo out performed both antennas on the air 100% in contact's with the Copper Forum CEF Member's giving me feedback and signal reports during the Sunday CEF Net's.

Result's / Specification's on paper mean nothing to me, but when 100% of the CEF Member's I have had contact with on the air tell me it is OUT PERFORMING the Imax w/gpk kit and the MACO I tend to believe them.

During side by testing of this antenna since getting it in the air this antenna has give me an average of 3 to 5 S-unit higher feedback report's than the Imax 2000 w/gpk kit and Maco, I will stick with it.

Somehow I just do not think or believe the CEF Member's that have helped me in testing this antenna across the US on the air against the Imax 2000 w/gpk and Maco would give me false or misleading signal report's in helping with the testing of this antenna on 10/11/12 meters.

Remember "Gain" for a generic antenna spec usually represents where the peak power lobe is for that antenna compared to either an a) isotropic radiator (dbi) or b) a dipole (dbd). It doesnt mean much with out knowing what angle the lobe appears. IE.. if an antenna has 10dbi gain at 90 degrees, while the 10dbi sounds good, unless your working Mars it wont do much REAL LIFE good. CB antennas simply stop at the generic gain rating.

But more importantly and I think this is what Lon is getting at is there is another never published gain figure- "efficiency". If an antenna's wire or radiating element is a 1/2 wave its pattern gain may be 2.1 dbi, and you may go as far to say "at 25 degrees when mounted 1 wavelength above ground", but what is never mentioned is how much power is lost in the matching coil or through a really thin radiating wire? a 3db loss would equal 1/2 of your power lost. so your 2.1 dbi just became -.9dbi. Thats negative. Please note the losses can exceed 3 db in some popular, poorly designed antennas.

3 to 5 S units better than an IMAX?

lets see, since each S-unit increase means a 4x increase in output power; three S-units means a 64x power increase (starting with 5 watts, you would need 320 watts to gain 3 S-units)

a 64x power increase equates to just about 18db gain.

somehow i have trouble believing that there is an 18db gain difference between the IMAX 2000 and the sigma vertical.

sorry, but i think someone is yanking someone else's chain here.

"somehow i have trouble believing that there is an 18db gain difference between the IMAX 2000 and the sigma vertical. "

HOLD IT .......

As someone has pointed out GAIN is what you see in your direction.

Now if the I-MAX with GPK-1 has a take off of lets say 35 deg and the SIGMA say 5 deg you would see a BIG difference say from Lon's place to FLORIDA where I live.

To correctly test you must have controled conditions

NOW my 12AVQ with a GPK-1 and 6 HAMSTICKS PLUS 3 more radials cut one for each band a total of 13 radials is ausum on all 3 bands ..... it was ( COUNT THEM ) 7 "S" units better than a A-99 and that was measured at 4 diffrent locations .....

Now how would that compair to Lon's SIGMA .... I have no way of knowing. BUT LON was 20 - 40 over "S" 9 here in SEMINOLE last sunday while Hal was at best "S" 6 ..... THATS A FACT .....

There are so many factors when measuring " GAIN " that again unless you do it from the SAME location and do a E AND H plane plot it becomes a bunch of JOGUNN nonsence as meaning less as AUDIO GAIN.

ONE last comment ... the QSL cards from last Sundays net are in the mail !

I heard my name being used in vain...

Well, I have to start by telling you that you guys are right. The only way to achieve the kind of gain being claimed here is with stacked elements. Since this antenna does not have stacked elements, I am very skeptical of the gain claim.

However, since I have not seen one of these antennas in person, it would be really unfair of me to make a firm comment. Lon has one in his possession and I have to go along with his claims. That is not to say that he is not mistaken or may be making uncalibrated measurements and interpreting them incorrectly. It just means, he has one and I don't, so anything I say is pure speculation based on physics and design precedent fact.

You can certainly increase the useable bandwidth of a 5/8 wave ground plane antenna with a large diameter tubing to make the tapped coil feed system, and make more turns in a smaller diameter, to a point of diminishing return. I can see how this antenna may achieve broader bandwidth, but I cannot see how it would produce substantially more gain to meet the level claimed.

When they are released, I would be interested in reading what some of you guys find after using them.

It would be cool to see a collinear vertical for 11, albeit huge!!! I was hoping my article would bring to light that some antennas do not publish losses due to poor matching sections or inferior parts. An isotropic radiator is an antenna with zero dc resistance, and has no heating loss. It is measured in free space and has no pattern gain. even the theoretical isotropic radiator if brought out of free space and towards a ground will begin to exhibit a pattern with a flat bottom and a lobed pattern. The theoretical antenna would still have zero loss as a whole, it would just change shape. now if a resistor were to be placed at the feedpoint (representing a lossy coil) it would still (as long as there were no reactive components to the resistor) have the same pattern, just less of it. It's not so much that the Mantova exhibits magical gain, it just may contain less loss due to a more efficient matching system, less dielectric loss and in comparison, a larger radiating area. I could easily see how the Mantova would beat an IMAX, I would think the Maco would be too similar to notice. If the radial system on the Mantova was better, and perhaps the matching section has a higher q, I could see how it could win over a Maco or other aluminum 5/8 wave antenna with similar construction. I myself am a vertical antenna enthusiast, and I think it's great Lon is putting this much time in really testing this. It's going to come down to how much better for how much more money, and I think that's exactly what Lon is trying figure out.

I'm both intrigued and excited to get my hands on one of these. If it can perform even one full S-unit in tx/rec and be tough enough for these upstate NY Winters, I'm all for replacing my old Imax. Since some of us are limited to height and type of antenna we can use on the house (in my case, I have a thing called "the wife"), then this sounds like my best bet for an Omni on a 30' mast, unless its performance drops considerably when mounted lower than 36' (one wave length).

P.S. Signal meters are supposed to be calibrated to 1 S unit = 6db, but I have rarely found that. Using an RF signal generator I have found any where from less that 3db to 6db, and most of the time its not linear, like 2.5db from a 1 to a 2 and 5db from a 7 to an 8 etc... The important thing is did it produce a noticeable difference in signal. Would it have made it through where the other antenna would not have.

$59 for my 1st maco v5/8 back in 1986, and i'm sure it has a few more good years in it, a 2nd, NIB that cost me NADA, and now a v5000 that just cost me a 2 transistor generic junko amp (cost:repair to a cobra 29).....hmmmm, that comes out to an average of $20 per antenna! or, better yet, LESS THEN A DOLLAR PER YEAR! and remember, it's only 22' above the ground, so i can still raise at least 14' to improve upon what i already have. i don't think ANY new vertical could ever be as cost effective as what i've got! and i KNOW it gets out!

How long does it usualy take to test antennas? It seems to me that 16 months is a very long time if these antennas really work. A few months would have told me anything that I needed to know about TX/RX,AM/SSB,weather,wind,rain,snow,ice and everthing else.
"somehow i have trouble believing that there is an 18db gain difference between the IMAX 2000 and the sigma vertical." I agree that 18db gain seems way to much. If it's that good it would be the best antenna in the world. And everybody would already know it.

The most important factor of all, that seems to be missed here, is the takeoff angle.

Gain means absolutely nothing if all the gain shoots over the top of the station you are trying to communicate with. If you have a 5/8 wave antenna close to the ground and a 1/4 wave antenna close to the ground, to a station 10 miles away, the 1/4 wave would have 6 or more dB gain over the 5/8 wave to that station. However, for short to medium distance e-layer DX, the 5/8 wave would have substantial gain over the 1/4 wave.

So, what Lon experienced is entirely possible. There are far too many variables to consider his findings scientific, so that is why the antenna range was invented. Since that antenna hasn't been on a range, we will have to wait and see how it performs for different people in different situations.

Unless I missed it, is this antenna assembly fairly to standard...measurement of the sections...the ground radials into the bottom assembly<already>, and on the vertical elements, are they premarked or have indents for the measurements or do we have the old school of using a tape..

THANKS

Revpo,

It is one of the "EASIST" antennas to assemble I have ever used or assembled.

There is nothiing to measure and assembly time is about 15-20 minutes with a "helper ie: 808xyl" and "Plenty" of room.

Each section fit's into a re-inforcment sleeve at each joint for added support/strength at each section.

The ONLY thing adjustable is the Coil which I made "NO" adjustments to as I just bolted in on to the factory holes.

Then connected the coax and mounted the antenna on the tower and started talking.

Do I dare ask if the Turbo is coming in '08? Or do I shine up the old RatShack .64 wave, throw it up there and hope for the best?

Tech 808> Is there anything still going with the Sigma Turbo or any news about these. Did the deal go "BUST" with Coppers, or is it still a go. Surely by "NOW" there should be some kind of response with Leantenne of Italy about these. You know Sirio Antennas of Italy really does well here in the states and surely the Sigma Turbo and that 3 element beam really should do well here too.

Something else to remember when testing antennas is that if using a skip signal as a reference one day could be better than another.E skip tends to be of a higher angle unless its multi hop which can be lower.
Ever switch between vert and horiz when using a dual polarized beam you will notice that sometimes the signal will be better on one than the other this is due to polarization shift which causes fading.So a vertical omni antenna may work better some days than others.
As was mentioned earlier there are many many variables when testing antennas and when Tech 808 did his testing he used a consistent station setup time and time again with the same results!! Does the antenna of this type have that much reported gain,no,but what ever works out the best is all we can ask for and I am sure when Copper gets the antennas in stock Lon will post the info.lon tnx for all the info you have posted so far with your reviews and yes we don't all agree with every ones opinion but what works for me may not work for anyone else.

I think for a while it looked like the Sigma Mantova Turbo was the "best" Omni out there. Now maybe other models that are competitive (Sirio's Vector 4000, 827 & 2016, the Maco 5/8, etc.). If we could see the results from Lon's tests, it would be a great start to see what direction to go in. I may not even wait for the Turbo if we're talking .25 of an S unit in Tx/Rc. I guess I'm guilty of getting overly excited for a product not available in the US yet. And I'm NOT paying the shipping to bring one from UK.

Hey Dale
I would go with that Sirio 827 if I was you. That one is very CLOSE to the Sigma Turbo as you can get.I own one of these for about 2 years and it is also VERY EXCELLENT. And worth every bit of of $115.00. It has held up really well for me and would be a much better choice than the 2016. Just wanted to let you know. I still wish I could aquire a new Sigma Turbo, Oh Well maybe one of these days.. Maybe?

You can't go wrong with the Siro S-2016, I replaced my Maco 5/8 with one, , flat swr, hears better and gets out better, high quality material, and 20 minutes it is up and Listening.
