Re: Really OT: Inside-the-vehicle HF antennas (possible bonus points)

Ummm ... no. Nor is the wife going to buy it on a family car.
Operating with my K2+Alexloop on a small hill in a local park once, I
was approached by two Sheriff's Officers, one had his gun[or Taser] out.
Someone had reported a spy, or CIA agent, onthe hill and they wanted to
to see my ID. Strange how a small radio, a mag loop antenna, and an old
guy who is obviously way past his spy-hood years can conjure up so much
suspicion in the ordinary folk.

Fred your close to CA and also perhaps you were mistaken for a Russian.
You know how it is these days.

Would tell a story but its too long and OT how I was mistaken for
Russian spy in
Shanghai in 1990, taxi driver got the idea and ratted me out. Carrying a
telegraph key and papers to operate at BY4AA.

In reply to this post by Matthew Cook

OK, get a big fiberglass spoiler on the back and cram as much wire as you
can in it. The feed it against the body via An autotuner on the inside of
the trunk lid. After showing her the drawing of that you shouldn't have too
much trouble talking her into a screwdriver antenna.
