Sound insulation and aerial connection

I have started sticking in the sound insulation now.

I also visited a CB Radio place, which shares it’s premises with a PC repair place. The CB guy was not in, but the PC man was very helpful and suggested how I might fix my poor CB radio range. Turns out that I had isolated the aerial too well from the body work. He explained that the negative of the aerial should be bonded to the body of the Land Rover as the body acts as one half of the antenna.

The silver part in the image above is the negative and is now electrically connected to the bracket and body, where as the copper centre part is the positive is isolated from the body. I have not yet tested this configuration, but I have my fingers crossed.
