Already mentioned but in a bit more detail. Clean everything and be certain the ground side of the antenna is solid. The antenna screws onto a post. take off the antenna and squirt contact cleaner in the hole and wipe the little threaded stud. Inside the tour pack, disconnect the antenna lead and again with electrical cleaner, wipe the big and small pieces of the male connector, using a Q tip and a pipe cleaner clean the large and small portions of the female connection. Repeat that with every connection up to and including the one into the radio. Use an ohm meter and verify the center lead is solid all the way from the stud holding the antenna all the way to the male pin that goes into the radio. Now reception should be as good as it is going to get with one more thing left to check. See if the ground side of the antenna lead is grounded even when the lead is not plugged into the radio. If it isn't run a grounding wire from the ground side of the antenna mount inside the tour pack and run it to the frame. If all of that is good, you are stuck with what you have. Function over appearance is my style. I tried a 51 inch whip antenna and things got better. It isn't a 1/4 wave or 1/2 wave or anything sophisticated but reception improved with it. Any chance your CB antenna and broadcast antennas are on the wrong studs?
