I'm hoping someone who is knowledgeable in radios can help me figure this out. Its driving me nuts. I bought a new Uniden Bearcat 980 cb. New front fender/hood mount, new antenna spring, ran a ground wire from mount to fender bolt. I bought a new coax cable. All connections are tight. I was getting an RF out fail on the radio diagnostics but everything else pass. Took all the antenna stuff off and redid it nice and tight. Now I'm getting voltage pass, RF out pass, antenna fail. My antenna is old. Could that be it? My SWR is obviously off the charts high. Coax to spring, through the mount then antenna to spring. I also put ferrite cores on the pos and neg wires going into the cb and connected power directly to the battery.
