My factory motorized antenna died in my 95 caprice. For life of me I cant see how to remove it without pulling the fender so I got a replacement gm non electric antenna frok the parts store. Only issue is its gt a short cable so right now its on my dash but the reception is crap. Does it need to be mounted to the body? Also, is the fact that I didnt hook up the on/off wireto the new cd player harness for the stock antenna causing an issue?
