Going to add this here because it may come up some time and save someone a lot of trouble.
If you use a Firestick (or maybe similar) "Heavy Duty Stud Mount" like their K-4A Model. Make double darn sure you get the flat and lock washers and the nylon washer in the right orientation. Otherwise you will get poor to none receive or send but yet get real good SWR readings.
They all go on top.
On the Antenna screw on side - NOT the Cable screw on side.
And from top to bottom its Lock, Flat, Nylon
I just got through completely going back through an install including removing and replacing the unit (a Cobra 75 Wx hand held) only to find out that the new Radio I installed also had good SWR but poor receive too! However this unit had a "Antenna Check" test that showed "failed". So I knew then I was onto something other than a bad radio. Replacing the cable and double checking the ground connection found nothing. Finally realized I had installed the washers all backwards. I was able to dig the back of the package out of the trash and look at the diagram and low and behold I had reversed it. I had put them all on the bottom. 180 degrees wrong. Flipping them back to the top fixed the problem. This wrong orientation was probably grounding the wrong portion of the cable and that was the problem. Good ground was present but it was in the wrong place.
So double check that and realize that this is an important portion of their mounts install.

The antenna has the largest influence on how well it works, especially on a Jeep.

A little late I know. I have a 2010 jk, antenna mount on stock spare tire bracket. My swr on 40 was a 5 and on 1 was 3.5. couldnt get it lower. I switched to a k40 antenna and ran a 10 gauge wire from bracket to frame. I cut the wip an inch at a time and got swr to 1.3 on 40 and flat on 1. If your swr is higher on 40 than channel 1 then you need to shorten if it higher on 1 than on 40 you need it longer. I ran 18 feet of coax.

|Bignuke||Thanks, I finally got it to work... I have a new antenna, seems to be 4' long.. as you said. Thanks though.|

call or go to this website, they may be able to help or refer you to someone in your area, they are the only people i let work on my radios, been in buisness 15yrs that i know of. i had similar problem try changing to an antenna that needs less ground, like a fransis 4' cb24b, thats what i had to do.

|Jerry Bransford||Use a SWR meter to tune the antenna (set its length) for minimum SWR on channel 20 which is is the mid-point in the CB's band of frequencies. That will provide proper tuning for the antenna for the entire CB band from channels 1 to 40. Tuning the antenna for minimum SWR allows the antenna to transmit all of the power your CB is capable of producing.|

I still haven't fixed... I picked up a new Coax cable so I might go replace the one I have now.
Can anyone inform me what to do to test it? Go to channel 1 then what and all that? Please

|terrible2||Well that firestik website has the procedures, but I dont have all the same knobs. I got the manual off the website, but never really found out how to work it. Im coming to SD soon, want to help?|

Pull the cap off your antenna. There will be coiled wire under the cap.
Assuming that you plug the SWR meter into the radio and antenna connection to the radio and key to get your SWR, you'll have to shorten your antenna. Just by snipping a short amount of wire off and re-checking the SWR, you can tune the antenna to the radio.
The procedures for what channel to start with are there too.

|terrible2||I have a SWR meter, I tried tuning it today, no success. I have KW Firestik and I believe according to the Firestik website to unwind some coils by making a slit into the plastic rubber on the Antenna. But Jerry made it seem like I would have to actually cut part of the antenna.|

|terrible2||I understand that your CB needs to be tuned to your Antenna, which I will soon be doing with my Cobra DX IV and 3' Firestik (KW series). Ill need to take a hacksaw or dremel cutter and do 1/2" cuts correct? Now what ive also heard is that you can also tune your radio, is there any device we need to do this? I hear that the radio guy opens up the cb hooks up something, turns a screw and then is finished. The reason why im asking if I can do it myself is because I hear it costs $15-$20, my CB only cost $15 I dont think its really worth it to invest double the amount for such a cheap radio|

I am preparing for an installation of a Uniden 520 with a Firefly FL4......
As I am waiting for a couple items on order, have been doing some research and found this on the Firestik website, a wealth of CB information...

#1 4' Wilson antenna. Yellow strip at top is the top of the antenna.
#2 Modded Mount with mount tape showing. I did this to protect the paint and to help secure the antenna. It aint going no where.
#3 Another toy
#4 Yet another toy.
I will never grow old. Just watch me.

Happy Customer and Forum Member
Bought the Jeep Uniden 510 kit from Right Channel Radio. The only issue was I ordered the wrong antenna mount. After some slight mount modification [cutting and grinding] I attached the antenna mount to one of the stock tire carrier bolt holes. I had great continuity to ground. Installed the rest of the components. The hardest decision to make was were to mount the radio. Drove out to an open space and followed the directions given above. I got 1.8 on channel 1 and 1.6 on channel 40. Good enough for me. The wrench that came with the WIlson antenna would not bite into the set screw anyways. Either way, the radio worked fine from the get go. Thanks for the above info all.

One more note to add when trimming lengths of wire that comes out of the top of Firestik's more basic antennas that do not have the brass tuning tip. Cutting 2" of wire off at a time is too much length to be cut off all at once. Cutting 2" off might mean you went past the point of minimum SWR and you'd never know it. Instead, I'd be cutting more like 1/2" lengths off at the most. The antenna length at which minimum SWR is achieved is fairly critical and it's easy to miss by adjusting its length too much at a time.
One more thing... most cases of high SWR that can't be tuned down as expected are usually a result of the mount having either been misassembled or it not having been grounded well enough to the tub. The mount must have an adequate surface area of bare steel to bare steel connection so that usually means grinding paint off whatever you're mounting it to.
And a misassembled mount usually results from having either left the nylon/plastic insulated shoulder washer off, or not getting it installed and centered properly. The insulated shoulder washer's purpose is to insulate the whip part of the antenna from the mount. If the antenna itself touches the mount, the antenna will be shorted to ground and a very high SWR will be the result.
The below illustration shows a typical antenna mount and how it should be assembled. Take particular care in seeing where and how the insulated shoulder washer is supposed to be installed.

|crashedking||The light tells him that there is reflected power. This only works for a generic VSWR meter and if the radio has not been tweaked, it will be reliable. The light never turns green. The nylon washers separate the center conductor to the ground. You must have no connection from the center conductor to the ground. This type of antenna does not have a capacitor, and should read no continuity center to ground on the radio connector. Your Antenna selection is not the best for this application. Because behind your soft top is your role bar, it runs parallel with the top load antenna. You will never achieve the best match because when you drive and the antenna moves it will radiate to your ground. The role bar and the power being radiated will cause high reflected power, the red light. This does not mean that this antenna will not work there. I cant tell what type of fitting you have from the pict. (The lower fitting). Leave the antenna connected to the bracket, disconnect the PL259 connector from the radio, take a OHM meter, what does it read across the center conductor to the barrel ground? Hopefully no beep or continuity. Nice bracket and CB. Who installed the PL259 connector on the radio side is it crimp or three piece? Your problem can be solved easily. Quit cutting the antenna, you may have ruined it. Start with what I have told you first.|

Progress. How is the radio wired in the Jeep? Hot to _______ ground to_________
Do you have the instructions on the radio? Does is tell you what that light is for? (sorry, it's bugging me that it even has a light)
And don't forget:
1. Remember to check for continuity, shorts and opens in your coax and mount installation first.
2. Take measurements in an open area with the vehicle's doors and hatches closed.
3. All measurements should be taken with antenna tip on, unless you do not plan to use the tip in normal use.
|05-27-2009 04:31 PM|
I think the antenna light means that it is not getting to the antenna...? (no signal maybe?)
Yes when i removed the washer it went down in the green (to the 3 on the SWR)
And yes I do.
