[FQP] [FCG] FQP Mobile antennas

[Jim Stahl]

Does the antenna check out normally on an antenna analyzer? Can you run low power without the radio going crazy?

You might also consider, if you haven’t already done so, a common mode choke at the antenna feedpoint. That is, wrapping several turns of coax around an appropriate ferrite core. K9YC has written extensively on this. It may be more of a bandaid (sorry, bad pun) than the real fix, but it might get you the few db edge needed to make the radio happy.
