[Elecraft] Antennas for KX-1

[Paul - VE1DY]

I was out of town on a business trip this week, which gave me a good
opportunity to try the antenna suggested by Bruce.  I used his 68'
with the 33' counterpoise.  The kx1 obtained a flat match on 20, 30
and 80, but 40 was 1.9.

I then tried Ron's suggestion.  I had a 13' piece of wire so I wrapped
it around my glasses case, which was approx 1.5" x 2.5", and this gave
me a flat match on 40, but drove the swr up on the other 3 bands.
It's not much trouble to clip/unclip the glassed case coil, so I was
quite pleased.  I will now make a small coil and keep it with the
antenna.

This set up worked very well for me.  Thanks Bruce and Ron.

Paul
