Hi guys. Is there such a thing as just a horizontal beam? I woud like one to use when I am on SSB on CB. I have always been told it does better, etc. to use horizontal beam for SSB. Does anyone make a small one that I can get? I don't want something with 10 to 12 foot boom. Is there maybe a small three element horizontal beam being manufactured? The smaller in size the better. Thanks.

For performance boom length is important.
Even though you state you don't want a
boom length of 10'-12' the Maco M103 as
Lon says would be your best choice.
They make no other beam that i'm aware of
that would mount just Horz. that would
have a shorter than 10' boom length.
Consider the Maco M103, its a good choice.

Thanks guys. I had looked at that one on copper site, but viewed it as a vertical beam. Are you telling me I can turn them so they will work horizonal? Just want to make sure I understand. Also, which coax would be best to run with that?
I do not use linears on my cb's. Thanks.

 What wasn't said is that the Maco M-103 is most times pictured vertical, But any yagi configured beam will run horizontal and much better than vertical.

Keith,
The rg213 coax that copper carries will be very efficient to use with the M103. The combination of good coax and that antenna will do a fine job for you.

Best of luck on your antenna project.

9913 for long runs over 150ft.
Otherwise RG213 works good.

QUADS do a great job.
HISTORY .......
The quad antenna was developed for HCJB short wave radio because they needed a directional high power antenna. In 1939 a group of engineers had to solve a problem of the needed gain and the fact this station was high up in the andes with all the problems a mountian location has. The rest is history! |

QUAD ANTENNAS RULE! 
So far since I started in radio in 1963 I have not found any antenna that will out perform a Quad.
I LOVE my QUAD's
PS,
I even asked Ken at Anttron to look into re-designing and building the 2 Meter Antron Quad-4 antenna like I had many years ago again.
And maybe a Anttron 6 Meter Quad?

I was talking Yagi antennas Hollowpoint445.
He asked for a Horz only beam, so, my
boom length comment was directed towards
Yagi's beams only. Quads are a different

The PDL-2 would of came close to the
performance of a Maco 3 element.
Patzerozero---My friend awhile back
cracked his hub for his PDL-2. He
cut out some (darn forgot name of stuff.
Lenox or Lonex, anyway its a very hard
plastic thats really tough. He cut
pattern out and glued it against his hub.
Things bullet proof now...LOL |

Ok guys, if it were you, which way would you go? I can probably get this PDL II back, cause the guy never put it up. So based on fact that I am looking for smallest horizontal beam, would you go for PDL, the Maco M 103 3 Element Beam that Lon suggested, or the Signal Engineering SuperHawk that Hollowpoint suggested?
Now keep this in mind: I do not want some great big thing up in the air. I run the cb with no linear amps. Antenna would be mounted on a 50' Push Up Pole that is so heavy it takes two people to pick it up! Which brings up a great?. How high do you have the horizontal beam? I will also use my Super Scanner for a omni directional signal plus vertical beam. The PDL is no longer made. If I talk across USA fine, if local fine. I just want better performance to do SSB, that is why I now have the interest for a horizontal beam.
So place your votes and lets see what we get. And thank you to everyone for your input. And as always, all cash dontations are accepted.

Yeah, he made a pattern out of lexan, drilled
the holes out for screws, drilled larger hole
to slip on PDL-2 boom and cemented in on
to the broken hub with strong glue cement
from Pep-Boys. Man, it strong now! |

Ok Keith here goes my opinion.
After seeing both a Signal Engineering
Superhawk and PDL-2, the PDL-2 looks
better made to me. After years though
the hubs seem to crack and break on PDL-2.
So, i would reinforce them with Lexan or
something right from the start. The PDL-2
can be turned with a TV rotor. The PDL-2
is both Verticle and Horz polarized, so,
it requires 2 coaxs.
But, i also like the Maco antennas....LOL
I,m not sure whether or not the M103 could
be turned by a TV rotor or not though.
Maco M103 requires 1 coax and can be run
either Verticle or Horz.
I can't make up my mind either....LOL
I would go for the Maco M103 (Horz) or
PDL-2.

that's what i was thinkin', Sg569. just gotta find 1 now that costs 'take it away free' or somewhere in that price range!
man, this keith character's just stockpilin' or givin' away grants & PDLs...somebody's gotta straighten him out!
the reason i'm looking for a PDL, (& i'm not even sure i would rush to put it in the air just yet, you know, too many antennas-houses close together)
is the DUAL polarity & RELATIVELY small size. a 3 element flat side PROBABLY doesn't look as ostentatious 35' up, but I KNOW the moment i put 1 up i'd need vertical directivity. a quad, the PDL in particular gives the best of both worlds & is considerably smaller then if you were to cross polarize 2-3 element yagi-types. keith, if i wasn't worried about the neighbors seeing a PDL as an eyesore, i'd get it back & go that route over the 3 element. having helped put more then a few up back in the '70's & '80's, i know how easy PDL's were to tune & install, & they took a pretty good beating. i've seen 808's pics of his SE quad holding the ice off of the ground, so i suppose they are pretty well built, too. i've heard about tuning difficulties with the superhawk vs the bigger SE quads, due to small size being more touchy, but honestly couldn't say. the ONLY reason i'm in search of a PDL as opposed to just getting a superhawk is the hope of coming across 1-REALLY CHEAP!
GET THE PDLII BACK & GO WITH THAT ONE!!! |

Quads can be either horizontally or vertically polarized. The polarity depends on where the driven element is fed.
Incidentally, the PDL2 and Superhawk both have the ability to use either polarity. |

Hey Pat. Let's see: Uniden Grants = 2 new in box,
Cobra 148F GTL (Malaysia) = 1 new in box.
That isn't much stockpiling. Anyway, I only plan on getting two more Uniden Grant XL's before this guy sells them out. Then maybe we can talk about stockpiling. How many do I have to buy Pat to be considered stockpiling anyway? I might not have enough money for that. I am not rich like
Bruce or Lon.
In all seriousness, the Uniden Grant XL that I currently run is the BEST radio I have ever had in 30+ years of CB. That is why I have thought about getting at least one more. One of the Grants that I have new is the LT. I just prefer the XL. Will be glad when I get the LT sold, so then I can go buy the Grant XL.
I sold the PDL II cause I needed money to pay bills. Sometimes a man's gotta do what a man's gotta do.
Not to worried though, cause I STILL do not have the super scanner up that I bought brand new two years ago. Right now it is storming like crazy, and when that happens, that is when I am glad I do not have anything up in the air.
Take care.

Keith, check out my pix
Thats a 3 element maco with an antron 99 mounted above it. I used a tv ant rotor to turn it before i got the Alliance rotor. The tv ant rotor worked just fine. The Alliance was just easier to mount inside the tower.

Thanks DX 431. Are you happy with that three element Maco? I have a heavy duty TV antenna rotor that I had bought for the PDLII. Shouldn't it be able to turn that three element beam without any problems? Thanks.

I have to be happy with what I have for a beam, rotor and vertical antenna. I have the PDL-ll, Radio Shack $70.00 rotor, that has no trouble what so ever turning it. and the vertical is the I-MAX 2000.
Living on Social Security and not able to work because of a bad heart and legs, is not easy when you have a high dollar radio hobby to keep up with. Who wants to work at almost 68 years old anyway?

PDL-2 and Maco M103 are both good antennas,
so, whatever you decide you can't go wrong. |

Guys I sold my PDLII. I was kinda concerned about total size in the air of that antenna. The Maco three element looks like it would be a ok in the air without problems from wind, neighbors, etc. No wires to worry about getting stretched, just a good (in my case) horizontal beam, which is what I am looking for. Then I can point that beam North and make sure that Lon hears me on Sunday nets! Thanks again for everyones input. Yea we all cut up on here, but when it comes time for real solid information, we GET IT!

Keithinatlanta,
You mean wires on a Quad can get streached?
My SE Quads looked like that for about 5 days until the Ice Melted from an ICE STORM we had and then bounced right back and looked like new again.
And all that ice sounded like BOMBS when it started falling off and hitting the roof.
They have been up for over 2 years now and also survived the 85mph Wind Shear that took the Imax and guyed Rohn 50' push up down with 6-3/16" guy wires on it.
And the Wires re-turned to the original shape and No Streaching and Still tight. 
Moderator136 / Lowpowerhal seen it when he was here and it bent that puppy FLAT in half and layed it on the roof.
Oh and the I-Max also survived the Ice Storm and the Wind Shear, But the 50' Rohn Push up Pole with 6-3/16 guy wires did not.

Hey Lon, I’m curious about your pushup pole failure.
Doesn't a 50'er have five sections? If so exactly where did you have the 6 guy wires (two sets of three I suppose) attached and where did the Push-up fail, at which section?
Did you have the top guy at the top of section five near the base of the Imax, or was it at the top of section 4 about 9 feet below the Imax?
3/16's is pretty thick for wire or was it actually rope?
Was it guyed loose or taut?
In looking back and besides the wind, what do you think contributed to the failure, do you think guying it differently could have possibly save the pole?

When I lived back home 200 mles north of New York City. We had a South River heavy duty 50 footer none of the light gauge mast like Radio Shack sells. It was guyed four ways at every ten foot section. This is 35 years ago now and we used twisted steel guy lines, broken every 9 foot with the green color glass eggs.
At one time before cable TV, It had the Channel Master Crown heavy duty rotor and two large, I mean big TV antennas on it. This installation only came down once in a 3 week group of ice storms.
When it was put back up it had a larger yet Channel Master Super Color Crossfire TV antenna on it and this time it stayed up until the TV antenna was taken off and the PDL-ll went up in it's place. The one time it came down in the ice storms we lost everything, including the house roof. |

Marconi,
The 50' Rohn Pushup was from the base to the top extended a total of 36'
Guy wires were attached at 35' 4" right below the Imax and at 24' and then attached to roof at 14'.
Guy wires were tight.
The straight line wind shear took and bent it in half right at Roof Level and layed in on the roof with all of the guy wires still attached.
Imax was bolted to top section that was slid down inside of Section #4 and all sections were bolted together.
Straight Line Wind Shear is what took it down and it also took Turtles / CEF #165, Maco Alpha V 5/8 Antenna down at roof level and 36 Power poles around us.
Moderator 136 / Lowpowerhal works with pipe and after he seen it he said they had also had problems with the quality of pipe they had been getting lately also with splitting/failure like this one did.
Sorry but No, I do not think guying it differently would have made a difference.
I drove 36 miles over to Rohn in Peoria and they attributted it to Metal Failure after seeing the Pictures with the wires still attached.
As we used it as a Commericial antenna for the business they replaced it.
Problem was solved by adding another Rohn 25G tower just for the Imax instead of putting a push up pole again.
Our other Tower with SE Quads at 56', and Ham antenna's at 30' & 24' survived.
Also with 3/16" Guy Wires.

Thanks guys. I guess it will have to wait until I get this New Old Style Cobra 148F SSB sold first. But if I do go with one, it will probably be that Maco three element as I only want it for flat side and from what I read and hear, it will not take up a lot of "air space". Even though I am away from neighbors with trees and such, you just never know how they will react Thanks again.

Now Keith got me thinking, maybe I will sell my 2 new in box PDL-2s and get a maco 103 to put horizontal and put my imax above it or even better my maco v if that would work. only one tower and omni + directional antenna in one siple setup!HHHMMMMMMMM!
I will think about that for sure + if I get rid of my new in box Washington and like new Cobra 2000 GTL I could posibly buy or trade for a KLV400 or even a KLV1000.
I think I will be listing this stuff on an online action as soon as I get my new computer,my old one crashed 2weeks ago and DELL said my new one will be slow getting built cause there back loged.
Thats fine though because you get a better deal for having to wait.
Thanks for the Idea Keith!

Hello Everyone! I have ran alot of beam antennas in the last 25 years and I always seem to come back to the Maco 103-C 3-element beam antenna mounted horizonal... For the size and the old mighty dollar, they are hard to beat. See ya on the airways! CEF 610... Damon |

Hey DAMON. Thanks for input. College tuition is due in three weeks. Antenna will have to wait.

hey keith, a couple of 60's/70's antennas
u can make a two element yagi, if u really want a shorter boom and need to vary the direction.
also, a bi-square beam is not all that hard to make and is simultaneously bi-directional. but it is not rotatable, and as i recall, it is over 25' tall and about 25' wide (just the antenna). {a two dimensional antenna}. it also has ~3.7 db gain over 1/2 wave dipole. it can be vertically or horizonally polarized.
both can be relatively cheap to make.
something to think about. |

hey keith,
just had another idea.
make a flat side dipole. it too is bi-directional.
if u only want 2 directions (i.e. e-w, n-s, nw-se etc) use a wire.
if u want to vary the bi-directional, use 2 102" steel whips and a strongarm rotor.

Well I got rid of one new PDL-2 and was going to get rid of the other new one but I think i`ll keep it just to have and store for collection. I do know the wind load is about the same as the m103 and I seen both on 36ft towers and to be honest with you I think the
PDL-2 looks nicer in the air and I think it uses only the same space as a horizontal m103 maybe less.
I am still not sure what to put up. I will probly end up putting a PDL-2 up cause I always come back to that antenna and with the hills here in PA I think its a better antenna for my application.
I know someone who has a used PDL-2 that is only up about 8 months and in perfect condition and it will fit on my trailer assembled so I can bring it home and stick it right up.
Why are there so many antenna choices a person can do? I can never make up my mind!
