Hi there I'm just getting started with my new radio.When I hook up the RF cable as soon as I start to screw in the outershied to the radio I lose reception. When just the pin is touching I can receive.I bought a new cable thinking it was shorted.But does the same thing.I have a Kenwood Ts 480.Thank you for any suggestions.

It still sounds like a possible short. Work your way back to the antenna checking for shorts. What antenna are you using and what band are you listening to?

I have it hooked up to a AOR LA 400 loop antenna.Im just using it for reception for a.m till I can afford a tx antenna.With just the coax cable hooked up to the radio I can hear am radio.As soon as I screw in with the outer shield touching it goes out.It only works with center pin.I don't get it radio is brand new.

Does the center pin on the 3 ft coaxial act as a short wave.Then when the outer shield is hooked up it acts as a RF cable?Dont know but it's an interesting way to start out.

According to the manual that loop antenna has sharp tuning--you may not hear much until you precisely tune it to your receive frequency.
