[Mobile-Portable] Question about HF mobile

[Philip, KO6BB]

Brian,

I suspect that nearby buildings or other structures may be detuning your 
antenna.  I suggest that you park in a large open space, tune your antenna 
for best SWR and then when you're on your lunch break recheck your SWR at 
your operating location.  Nearby buildings, power poles, lamp poles, large 
vehicles, anything in the near field of the antenna can detune it.

I use the Hustler antennas, mounted at the top lip of my pickup bed (makes 
for a tall antenna) and it works very well.
