A good antenna is way more important than a good radio. A good radio will die a quick death without a good antenna. I have been out of the CB business about 10 years, but the K-40 was good and anything Wilson is unbeatable in a steal whip. For a pickup a mag mount steal whip on the top is as good as it gets, just gets tall. A very good ground is the most important. Check for SWR after you install whatever you put in. Anything under 2 is really good, over 2. 5 is not good. If you run a fiberglass in the bed you will have to put additional grounding to the bed to get your swr down.
