Wilson 5000 Magnet Mount CB Antenna

I guess this topic is cut and dried, but I have to ask the age old question. A bunch of local CB buddies have K40's and they dont do nothing but blow me out of the water. I have two co-phased radioshack "off-road" whips", but am getting a K40.

For those of you whom have a K40, what are your likes and dislikes? Performance? I know they are a bit pricey, but I've always been told a radio is only as good as it's antenna. Tnx.

484bluegrass I a have owned a couple of K-40 trunk mounts but they seemed to break where the whip goes into the load.
I went with a wilson 1000 trunk mount and I have had no problems with them.
All tough I have made some real good DXing with both antennas but I like the wilson better.
I hope this helps.

I prefer a Wilson over a K40. Owned both. Had much better Swr's with the Wilson and it handled power much better with lower SWR.

Got a wilson 5000 now...love it. 1.1 SWR

I noticed the bears around Indy always used the K-40 trunk mount. A great antenna but I will have to recommend a wilson. Guys like the trunk mounts but I use the Wilson Silver Load 6 footer. Has a tunable tip and I mount it wth a hole thru roof mount or what some call a beehive mount. Now when I want nothing more than pure DX performance I use the 96 inch Francis whip. 99% of my farthest DX contacts were made using a Francis 96 inch whip and the 5.5 foot whips. Needle on the SWR meter wont even budge a bit. Once a Francis goes thru about 2 Indiana winters they have them awful splinters! OUCHOOOO

Ok Mr. Rodeo Cowboy, have they convinced you yet to go with Wilson? I have had both, and to me it is Wilson hands down. Just a better built antenna that transmits and receives far superior to K - 40. And I do NOT run any power.

In meantime, I love the rodeo, so what do you participate in? Which circuit are you on?

Also, I thought I was the only one who ever ran that Francis 96" whip. I still have it and still love it.

Don't forget though, a K40 is still a great antenna. Mine did tend to crack as well, but it never affected my signal.

If you're not running an amplifier, they will probably perform more closely.

I have had both, although I never tested them side by side, when I ran no extra power, I didn't notice a real difference.

Ok, it looks like the Wilson has the majority of the votes here. So I thought I would throw out my 2 cents... I have a K-40 and I switched to a Wilson 1000 and my SWR's were kind of high I forget what they were as this was sometime ago. Plus I kept getting engine noise through the radio. I tried filters and such but the noise was still there, even tried to ground the truck with a braided cable still no luck. Went back to the K-40 and my SWR's went back down and the noise went away. I did some research and found that the K-40 has a Capacitor inside the base coil and the Wilson did not. The only thing I could think of is the Cap acted as a filter in the antenna (just guessing on that as I am not a tech.) Yes the K-40's do crack on where the antenna goes into the base but I believe there is a warranty that will cover replacing it. I have had mine replaced once before. Anywho that's my 2 cents...

And i'll step out of line here give me a good old
109 whip antenna AnyTime i get 1 to 1 SWR and Big
bandwith too.If i had to run a loaded antenna i go to a Hustler MO-1/RM-11S then if i need to go
in a parking lot with low over just fold it down.

I have used a K-40 trucker, it was good but now I run a wilson 1000 mag mount and like most here say, I take my wilson over the K-40 any day, although Al lafon has a good point if a big antenna isn't an issue for you, the 102 stainless whip is the best I think.

A friend of mine has a pickup with both the Wilson and a 102" whip. He switched between the two and the Wilson put the 102" whip down with ease. However the Wilson was a magnet mount on top of the pickup and the whip was bumper mounted. It would have been much closer if they were mounted at the same height. I have a Wilson 1000 magnet mount also. It picks up the fuel pump noise bad. The previous note about the K-40 is interesting. I have got use to the noise but don't like it. The swr on the magnetic mounts that I have went right to nothing. I had one of the other wilson 1000's that mounted on a mirror that I took back because of the high swr.

Danusee they have to be mounted in same place to be fair as we all know bumper mounts are poor at
best. This is why my whip on the 1/4 pannel is
my local antenna and i run a 102 on big magnet mount up on the roof for DX. Also run the Hustler MO-1/RM-11S on the roof.I have parked
on a open hill top when Dx is running and changed
from 102 to Hustler setup same magnet mount and spring coax just changed antenna out what i got was about 1 s unit more on rec. on 102 person i was talking to can't see a change. this is about as fair as you can get.

Hum mm,

Well I bought 2 K40's 3ft. I run a Dump Truck and mounted them on the mirror brackets that came with Truck. I cannot get the swr's down to a decent level. They are running around 1.8 right now. These are the 2000 watt antennas, and for now I am running barefoot.

Problem is sometimes my high SWR light on my Cobra 29 comes on and it worries me greatly that I will burn up my radio. I had to go with shorter antennas as I smack a few tree limbs in my business. Is there anything I can do to lower the Swr's on these antennas? Oh, I am also using the heavy duty stainless steel springs.

I have a KL 300P amp I want to hook up but I wanted to wait till I got the high SWR reading down some. Does anyone have any ideas of how to do this?

Thanks in advance

I have somewhat extensive experience in mobile radio/antenna/amplifier installs on large trucks so I'd like to comment. I'm not just "throwing out ideas" to you, but think one of the common reasons for SWR troubles (on big trucks) below MAY be your prolem.

First, let me mention in reply to the actual thread title "K40 vs Wilson" that I have a pair of "K40 Trucker" antennas I used for a while and I liked them very much. Honestly I like them a "very close 2nd" to the pair of Predator 10K's I own.

Now, I understand the problem with "low-overhead" on a rig, resulting in your choice of small/low antennas.

I've driven tri-axle, so know that most guys doing it will try to keep the antenna height down, and the mirrors pulled in as much as possible----given the amount of hazards & obstacles dealt with on a daily basis.

If it were me, I'd consider the following:

Although not your fault, nor were you given much choice, but the mirror-bracket mounting location for your antennas is a very poor one. So expectations can't be real high even to begin with. That is true for atleast the following two reasons...

An antenna needs a large horizontal metal surface DIRECTLY beneath it. Using a mirror-bracket gives you "nothing but airspace" beneath the antenna.

The other problem is that with the mirror-bracket mounting, it puts the antenna too close to the side of the truck----too much BESIDE the truck. You need to be away from AND above it. By this I mean it puts the antennas too close to the VERTICAL surfaces (not good) of the cab & door etc.

My biggest suggestions would be depending if you are going to stick with the two 3-FT antennas you have or not.

If you do keep and want to use them, I'd consider doing this. It may seem like a compromise but I'd move the mirror-bracket MOUNTS as far OUT as possible on the bracket, away from the cab. And I would also swing the mirror-brackets OUT as far as possible so that the antenna is again as far away from the cab & doors as possible. Any (especially short) mobile antenna too close to the SIDE of a metal cab will raise your SWR. Almost guaranteed. The compromise is, doing this will give you even less metal area beneath the antennas though. Still, I'd bet this will help and is the best of the two choices.

Now, if you are willing to buy a new pair of antennas, consider the center-loaded aka "oil can" looking types like the K40 Trucker (my preference) or the Wison Trucker 2000. With the K40 version I've found they are excellent antennas to begin with, have absolutely no trouble getting a low SWR or running a 2-pill amp through them (antenna rated for 7000W). I had them on each mirror like you do, in co-phase. Excellent results.

The reason why I suggest them, aside from that they perform , is for two reasons.

They are a TALLER (and safer) antenna, which is definitely what you need. An antenna NEEDS to try and be ABOVE the truck----not beside it. If not, that will definitely give you SWR troubles. Secondly, 3/4 of the K40 or Wilson Trucker antenna is thin metal whip. The whip will bend over virtually every time when encountering an overhead object. A fiberglass one will usually snap.

I see you put barrel springs at the base of the antennas to help prevent this. True, by leaving the springs off the antennas you will surely snap off at some point. Even with them on they are still fibeglass and will eventually take a hit and break. I've lost many fiberglass sticks that way, usually the passenger side goes first. Out of curiousity you could always try removing the barrel springs, just to see what that does for your SWR readings and if it changes them, but again you'll lose the antennas to breakage. Still, the metal whip types would both be taller and not break either. The best choice. Keep the short ones for your pickup truck or something maybe.

Two other things. If your mirror brackets are powdercoated like many are now, you won't get a decent metal-to-metal ground contact where the mirror-mount connects to the bracket. It needs metal contact.

One final thing I ask is because I've seen this many times: Are you running to both antennas with "actual 72-Ohm co-phase coax"?

I've seen many drivers (who don't know better) put a "T" connector on the back of the radio's SO239 jack and have two separate 50-Ohm coax cables go out to each antenna. Usually I think this is done when someone decides to "quickly" add a second antenna. They just buy the second antenna, a short piece of coax and a "T" connector to throw the second antenna up there. If this were the case it would definitely screw up SWR readings.

The real co-phase coax should be "Y" shaped with one connector at one end to go to the radio and it should split (or "Y") into two separate pieces going to each antenna. Sorry if you know all this but I've witnessed so many quickie installations like that I can't begin to count.

You may want to follow these links for the two antennas by copying them into your searchbar. Look at both, and see the comparison:

Fox hunter,

Thanks for the quick reply. My Truck has mirror brackets unlike the old swing old style. They already have a place to mount the antenna on, unlike the add on clamp styles.

My coax came with the Truck new and is co phased, alias, Y connected. I cannot move my brackets do to mirror mount style. I had though about removing the spring under the antennas, but was worried about the antennas breaking do to slapping tree limbs. I have that to contend with driving a Dump Truck...lol when I set my antennas Swr's, I did them one at a time with a separate single coax. However the Swr's are way to high I think. 1.8 seems a little high. Now for awhile the light on the cobra radio 29 didn't come on.I'm talking about the light that shows up when there is high Swr's.

After smacking a few limbs I noticed the light coming on. I looked at the K40's tips, and they are bent a little. I didn't try to straighten them as I thought they might break off.

I don't know if either of those antennas you listed in a link, will take the beating of the stuff I go through.I do want to install my RM KL-300P amp whenever I get this problem with high Swr's fixed.

My Truck has the Coax ran through the Dash and the Doors which would make changing it out a real pain.

Any other ideas come to mind?

Ditch the fiberglass and go with the trucker 2000 with the short shaft's. This is what I run on the tri-axel at work. The whips take a beating and the swr's have stayed the same for almost 3 yr's now. I have the same style mirror mount that you do.

Forgot to add we had the fiberglass on the truck when we got it and after a few hit's on tree's or what ever got in the way they started to get weak, fiberglass was breaking apart.

It's true a whip like I listed above will still take a beating long after you've broken 5 or 10 fiberglass sticks.

I bent one whip only once because I had it mounted very high on the late-model Freightliner Columbia I'd been driving. It hit a steel-girder overpass literally at 80-MPH on the NY Thruway/I-90 last year near Buffalo NY.

It was the K40 Trucker Antenna's whip and I easily straightened it (in two places) with pliers, back to like-new.

The majority of truck mirror-brackets can be pulled in or out----for adjustment and for "breakaway purposes". Perhaps yours can't, but that's unusual.

Like your truck, mine had a co-phased setup from the factory, and with factory antenna mounts already affixed to the brackets. As well as pre-installed factory coax. Yours, like mine, probably has very poor radio materials from the manufacturer.

Honestly, the first thing I did was take off the factory antennas and throw them in the garage for one of our other drivers. I bought two heavy-duty mounting clamps and mounting studs of my own. Also bought some Belden RG8X ("mini-8") 72-Ohm co-phase coax of my own. Let me tell you why.

Factory antennas, mounts, studs and coax are really of far lesser quality than even Radio Shack gear. The stuff is really cheap and low-performance.

After I disconnected the factory coax ends I took apart the interior door pillars and other panels and could see that each run of the coax was in 6-FT sections with cheapie crimp-on conectors. So there was a connector every 6-FT on both sides going to each antenna, the whole length (which is very lossy). Combine that with the cheapest type of coax made---and that spells "very poor signal". These coax cables are often run parallel side-by-side with vehicle electrical wires in the dash & door pillars, which is a definite no-no as well.

Yes the antenna warning light is definitely telling you that at times you're approaching very high SWR levels. You say that you have an SWR of 1.8 which, although not excellent, isn't terrible. It must be an intermittent problem because odds are when that antenna warning light goes on the SWR must be climbing much higher to light up the light. Those cracked and scraped fiberglass antenna tips are a bad sign.

If....you really are wanting to put in even a small amp and attain reasonably low SWR I'd strongly recommend with you going in with some coffee on a weekend, and run your own:

Quality whip antennas
Heavy duty antenna studs
Heavy duty stud mounting clamps
Good quality co-phase coax like Belden 8X

Those items above aren't that much really, a good investment. They can be purchased very reasonably from Copper Electronic's store here or from a vendor of your choice if need be. Check out Copper's catalog. They are far better priced here than in a truckstop CB shop.

Then your SWR will read much differently with new good quality gear and you will then tune your antennas knowing that the whole foundation for your radio and amplifier system has at least half a fighting chance.

Foxhunter,

Will this device help get my SWR's down? Also, Is it worth the money spent?

"Antenna matchers" also known as "Antenna Tuners" and "Transmatches" don't change a bad SWR. They will however change how the radio "sees" your SWR. It fools the radio into seeing a decent/low SWR, making the radio & antenna useable. That is not necessarily a bad thing. It is "a shortcut" kind of device and hides the high SWR problem.

With it, you will have a better system than you do now. But not as good of a system as you could with the antenna system tuned properly. An "impovement"? Yes. A "fix"? No.

MANY Ham/Amateur Radio operators have used antenna tuners successfully for decades.

For an extreme example----even any random piece of wire "could" be used as an antenna, by using an antenna tuner. It would actually give that random wire a decent SWR, when it would have had a sky-high SWR without the tuner!

There are some who view it as a bit of a "bandaid" fix, but IT WOULD WORK---and perhaps work well. Many radio operators SWEAR by them. They can be very handy, and I have one (a MFJ-945E) that I bought in a "package-deal" along with a Galaxy DX99V.

I personally try and get my antenna systems as close as possible to being right first, then have the option of using the tuner "to perfect" my SWR to apearing absolutely flat.

I have also a VERY large Ham/Amateur Radio "homebrewed" (homemade) antenna tuner for use at the home station here at the house. You'd be hard-pressed to find one serious radio guy that doesn't have atleast one antenna tuner.

I think the item you listed from Copper's catalog would most-likely give you a good SWR reading in your truck. There is NEVER any guarantee, but a very good chance.

I didn't see in the item's description that it specifically said it could be used "for mobile use". There's a good chance it can, but I didn't see it mentioned.

Maybe one of our members or Tech's here involved with Copper Electronics would care to share if they know whether it can for sure. I'll post as a separate thread linking to this one to get it noticed more if possible.

Also let me provide a link to the website "Hamuniverse" and it has a very simple and straightforward one-page explanation of how an antenna tuner works and why use one.

Perhaps other members will weigh in on this?

Bud1110,

YES, the AT-KW1 No Ground CB Antenna Tuner will lower the SWR that your radio see's and allow you to operate your radio safely.

After testing / doing a review on this product for the last 3 month's the answer is YES the
AT-KW1 No Ground CB Antenna Tuner
is worth the money.

Thanks for the replies guys,

I didn't ask if it can be used with co phased antennas or not. I only saw two connectors on the Tuner. Is this a problem then?

What makes the AT-KW1 No Ground CB Antenna Tuner so special with this no ground feature? I have used tuners of different types without grounds for years,currently using the auto tuner in my 920 which is not grounded and it works super?

That's no problem Bud1110 let us know what you do or come up with. It will seem then the AT-KW1 can be used mobile with success thanks to Tech808's information provided, he should know.

Using this antenna tuner will let you, very easily with the turn of a knob, "dial up" a decent SWR readng.

Got to looking at my antennas Friday and found that both of them has the outside skin coming off them. I put electrical tape around them and found that my Swr's went down, and my light doesn't come on now.

Strange thing. Just at the base of the antenna's is where they were separating.. I'm gonna buy two new antenna's shortly.. I may go ahead and buy the Tuner as well. It all depends on money at the time...lol

Thanks to everyone for all the help here..

Bud

Don't no much about trucker type antennas, but have had some different mag mount antennas Wilson 1000,5000 and K40s and some K30 antennas as others have said Wilsons will take much more power than a K40 or a K30. Of these four antennas the sleeper is the K30 for talking on 30 of the 40 channals with a under 50 watt Radio on SSB or AM, It will out perform the others hands down, it is so much better than the other three antenna you won't believe it. 25 miles to my base station and A-99 with a Cobra 2000GTL. In my car Cobra 148GTL a new one 3.5watts AM 12 watts SSB with on skip present, day or night. Just keep the output power under 50 watts PEP but you woun't need any more than that anyway........walterb

This Topic reminds me of the movie Cast Away (WILSON!!!!!)
So there you have it Wilson.

Hey Starface;

If you remember even Wilson had enough and swam away from Tom.

Wilson 5000 works great on friends Jeep mounted to spare tire bracket. When 4 wheeling at Bull Creek it comes in handy. One of the guys had a fiberglass 1/4 wave whip that became tree fodder.
