Thanks to Bill Parsons-AF6AE for the tip on the QST December-2005
article. Pulled it out and scanned it over (will read more thoroughly
later) but interestingly showed how 80/40m coverage varied by time of
day (which was demonstrated real-time in the 1980's on the Iditarod
trail working into Anchorage).
At home I only use those bands infrequently and mostly to talk out a few
hundred miles in Alaska. Somewhere I read that a 40-foot high
inverted-V would work well. I have a 50-foot tower mounted to end of my
house with Hygain TH3mk4 tribander at tower top so hung my 80/40m fan
dipole at the 40-foot level with end tapering down to 20-foot on one end
and 15-foot on the other. Its hung on a line NW to SE but that seems to
work out 400 miles just fine.
I am going to re-hang that antenna next summer with 80m wire at right
angle to 40m wire as the fan-style 40m tuning was affected by proximity
of the 80m wire. As I have written previously, I will also run this as
a top-hat loaded vertical on 160m/630m by shorting the 40-foot high
feedline.
I check into a weekly net on Saturdays (11am local time) on 3920 KHz.
NC is about 70 miles south in Homer, AK (KL7PM) and consistently comes
in at 30-40 dB over S9. He does run about 400w. I get at least S9
reports from him with my 100w and I hear other stations out as far north
as Fairbanks (400 miles) pretty well. Band noise runs S7 (K3 PRE Off).
3920 is designated emergency channel for AK and often activated after an
earthquake for tsunami watch.
