High SWR on CB radio?
My radio never has been able to transmit properly, and my friends with their CBs (they have the same kind as me, and their SWRs are fine) can't even hear what I am saying if we are parked right next to each other. This is very surprising, because I have a 4 foot long Firestik antenna.
So I borrowed my friend's SWR meter and measured my SWR. I have well over 3 in all channels, which is WAY in the red.
I immediately printed out Firestik's high SWR troubleshooting tips, and did everything it told me to do. I tried tuning the antenna as usual, I tried checking all the grounds and connections, and even changing antenna positions. Nothing helps at all. I was still in the red, and my friends could not hear me.
I thought that maybe my antenna or coaxial cable was at fault, so I borrowed my friend's working magnetic-mount antenna to try it out. With the different antenna, my SWR was worse.
Finally, I decided to just get a new radio, because maybe mine had a fried resistor or something. So i took my CB back to walmart, and successfully exchanged it for a brand new radio (without receipt or original box, for that matter).
And just my luck, the new radio STILL has a super high SWR, in the red, the same place as before.
I am all out of ideas. I have searched the many CB and off-roader forums on the all-knowing google, and nothing helps.
Does anyone have ANY ideas on what I can do?
