Hey guys I'm having power reflection issues with my CB radio. Swr is 1 but power reflection is over 8. I have a firestik II, Wilson silver coax, and a cobra lx lcd radio. Cascadia 2018 mirror mount. Any ideas at all? Can I run a ground wire from the mount to the frame at all?

The Cascadia has proven to be a hot mess in regards to radios and signal. Honestly, I'd spend the money and take it to a decent cb shop and have them sort it out. You already have the equipment so for them to troubleshoot and dial it in shouldn't cost much.

Hey Reaper, I drove 3 different 2014 Cascadias and each truck had an issue similar to yours. I gave a buddy my cobra 148 GTL for his cascadia and he had the issue as well using the after market mirror mount bracket. The swr was excellent with the door open but when closed it went bad. He took it to a cb shop and they got it straightened out. I would first just try running a seperate ground wire from the antenna ground side directly to the frame so you have a good and consistent ground and see if that fixes it.

Thank you so much! Do I attach the wire at the bolts or the clamp? On the antennae side...

I'm not a CB expert or anything, but is that possible? My understanding is that the only way swr could be 1 is if there was almost 0 reflected power. How are you measuring reflected power, and what does the 8 mean?

It is critical you attach the new ground wire to the ground side of the antenna which will connect to the trucks frame. So, it can not contact the center of the coax or the threads on the whip antenna that screws into the mount. The coax has two conductors inside it. One is the center conductor which goes to your whip antenna and the other is the outer shield of the coax which goes to ground and grounds to your truck frame. So, on the cascadia aftermarket door mount you can make a connection to the mount, bracket, bolts, or anywhere inside on the truck frame because each is electrically connected to the other. I hope this isn,t confusing.
