CB installers?

I'm having a hard time getting my CB tuned. I'm getting a swa reading of +3.
Does anyone know of CB installers in the San Diego area. It might be time to have a pro or someone who knows more about this stuff. I have a uniden 520 with a firestik 2, my antenna mount is a teraflex. Anyone have this problems with similar equipment?

How tall is the antenna? Which mount are you using? Have you tested your coax for shorts? Have you run a ground strap for the mount bracket?

With a little info I might be able to help you out.

Iceman will get ya all squared away.

FWIW, my bet is a failure to insulate the antenna base (#1 cause of >3 swr).

I'm using the tera flex mount bracket. my antenna is 4 ft. (Firestik II) I have run a ground from the bracket to a bolt on the body inside the cab. Don't know how to test coax for shorts, so I haven't done that.

Post a pic of the mount impossible. Do you have access to a multi-meter (voltage ohms amps) if so I can easily walk you through testing the coax. Does the antenna extend above the jeep?

Also that ground should be heavy gauge wire run to the frame.

I'm using 12 gauge wire. I'll try to relocate the ground and see what happens.

The mount is powder coated, should I sand down the contact area?

For the ground maybe, check the resistance from the outside of the coax connector to the ground wire so long as it is very low you should be getting good contact. Check the coax for continuity center pin to center pin, and outer to outer, then check center to outer.

I had to do that and add a ground strap when I installed mine this summer. After you sand off the power coat you should get a better reading.

We fixed it Saturday. After an Ohmmeter noted no ground connection to the bottom of the antenna mount due to the powder coating on the Teraflex mount, 30 seconds with a Dremmel tool fixed it.
