CB Radio Issue
I have been gathering parts for a CB radio and it seems I am now finished. Before I mount it on my overhead rack, I decided to test it. At first, I was not be able to get any sound from the radio. I figure it was a ground issue so I took some sand paper to the CB antenna mount and now I can hear a faint static noise if I adjust the squelch. My problem now is that either I am not broadcasting a signal or I can't hear anyone. I got an antenna from an 18wheeler. I have a full size Uniden CB radio and I tried to pop the cap off the antenna but it does not come off. I suppose it's not tunable. I know the radio works because it works on my little tractor trailer. I assume I am still having a ground issue? I read the instructions for the CB antenna stud so it is on properly. What could be my problem?

Broken coax? Coax cables do wear out or break over time. What are your SWR's?

Yes, Check the continuity on the coax at the radio end. If you can remove it from the antenna end also, all the better, then you can check for and open or short...

Well the coax cable should be working since it's the same coax I took from my rig. It does look like there is a little peice of the male connector part chipped off. I did try it on my rig and it still works with the peice messed up. I'm able to get replied over the cb. Do I have to ground the antenna with a ground wire? Iv'e seen some CB's with that setup.

The antenna itself doesn't get grounded but its mount needs to have a good solid ground. The mount insulates itself from the antenna when put together properly, just make sure the mount is getting a solid ground connection to the Jeep. Running a ground wire between the mount & Jeep is not normally enough to provide a good solid "RF ground" which is different from and more demanding than a normal ground connection.
