[TowerTalk] Mobile antennas?

[Jim Lux]

You might want to take a look at Q-MAC (an Australian company) who has a
very interesting take on a magnetic compact loop roof top antenna. The SGC
HF manual also talks about using autotuners and loop antennas.   For 40m and
a max 14' height antenna, you're looking a a compromise in any situation.
