Safe Transmission

Im going on a trailride tomorrow. My CB after I installed it has a SWR of 3 !! Yeah i know. I'm trying to figure out how to bring that down...maybe run a ground from the mount to the chassis or something? Im not 100% on what is causing my high SWR. Tuning the antenna doesnt seem to change it all that much. But I can hear other people on it just fine. Can I talk on it tomorrow? Or am I going to fry something? I have a Cobro 75 WXST, with a 3' firestik firefly mounted on an arizona rocky road mount.

It won't fry, modern CBs have built-in circuitry that reduces transmitter output in the presence of high SWR to prevent damage. That said, you may not be transmitting very far due to that reduced output. One thing about tuning for minimum SWR, the 'dip' in SWR is often very narrow in width so don't turn the tuning screw too far between checks of the SWR, you may be skipping right over the best SWR tuning point.

When you have a choice, buy American.
