How do I know if my CB antenna is bad?

Luckily, testing an antenna is a fairly easy process….Testing for a Defective CB Antenna

1. Using your multimeter, touch one of the probes to the metallic end of the antenna.

The Delta Tune controls the frequency your radio’s receiver is operating on. You may notice similarities to a clarifier control on other CB’s, and while both these controls do similar things, they are not used for the same purpose.

Does coax length affect SWR?

Coaxial Cable Length Does Not Change Antenna SWR.

Why does antenna warning light go out on Cobra 29lx?

Can’t have the coax being pressed or mashed, it needs to be roughted correctly to not be crushed ect. The coax can be tested by connecting a Dummy Load at the Antenna end of the Coax, the Antenna Warning Light should go out if the Coax is ok.

Close to Toronto ON. I’d say the wire is broken from being bent and swished in the door over and over. You could confirm this with a Multimeter.

What makes the antenna warning light go out?

The coax can be tested by connecting a Dummy Load at the Antenna end of the Coax, the Antenna Warning Light should go out if the Coax is ok. I hear a lot of guys having problems with the Wilson 2000 truck antennas. A local had the same SWR problems and we switched to a Wilson 5000 to fix it, it was mounted on a tool box just aft of the truck cab.
