That is a weird one. The whip you are using would be the first hing I looked at.each antenna I have tried with the exception of the 102 inch whip I tuned to get the final of 3 swr on ch 1 and ch 40, I purchased a firestick 4 ft and to get my swr the same on 1 and 40 I removed the tuning screw and even had to shorten the antenna.
I keep reading every place that it is a ground issue, I downloaded a wiring diagram last night, it indicates multiple dedicated ground locations through the vehicle, one just happens to be in the rear, I think I will try to put my antenna ground to it.
Thanks for the help !
Jesus antenna!...SHAZAM! Flat 1:1 swr on my 102 whip on every channel.
Bringing an old thread back to life....I've got CB issues that I need some help with.
I did a full detailing of the FJ after the rough winter we had. ......
Yup, I've taken it apart and put it back together about four times...still the same thing. I'm going to make sure all the connections on the mount and antenna are super clean - meaning NO dielectric grease in sight. I'm beginning to wonder if the antenna is shot. It's an 8 year old Wilson. When I park the FJ in the garage I bend the antenna over and slip it under the top rail of the roof rack so I don't hit the garage door. Maybe it finally gave up the ghost from all the bending. The good news is the new antenna coax I just got came with all new mounting hardware including a heavy duty spring. I added the spring on top of the mount to give the antenna more flex.Your target are the upper numbers on the first scale 0,1, 1.5, 2 right over the SWR lettering. the lower the better.
Retry all your connections, did you put all the pieces back on the antenna mount ? The little plastic washer between the antenna mount and the Bandi mount ? I got the same thing this spring when i changed my mount, undid everything, remounted and all was good.
A couple hundred feet down the driveway from my house. No other houses or power lines around. I replace the rubber cap every time I adjust the antenna tip.Where are you taking your readings? Out in the middle of nowhere, or inside your garage or near power lines or buildings? Are you replacing the rubber cap on top of your antenna every time you take a reading?
