My friend just has bought a CB radio from Radio Shack, and it does not seem to be able to pull in a signal and barely transmits a signal. He has check the SWR and it's below 1.5. The radio be bought from Radio Shack is the model that runs about $70.00. He is also running and 8.5 foot steel whip antenna, mounted to the side of the body. Is there anything wrong with this or what?????
