The answer to the problem is an old one in that it is difficult to get an HF antenna to work with a mag mount due to the low capacitance between the magnetic base and the vehicle body. VHF/UHF antenna mounted on a mag mount is OK as the effective low capacitance does not present a problem. I even tried a 3 magnet type of mount on HF with the same dismal results. Am told that if you can install a very short wide grounding strap from the mag mount to the vehicle body this can be the answer to the problem, but admit that I was never entirely successful with this either. There seems nothing better than getting a good metallic contact with the vehicle body to get an HF mobile whip to tune and correctly which is what I had to do in the end with a bolted on mount.
