The 400 mile distance gets me into eastern Oregon, Northern
California, and western Idaho. Not a whole lot of activity going on
in those areas. Being right on the ocean I don't start getting into
population areas until I hit, at least, Colorado. Quite a bit of
activity in Washington so that is a plus, but not like the big
population centers.
Yup. From my QTH 70 miles S of San Francisco, the next population center
is LAX, at 300 miles, SDG at 400+. It's 600 miles to AZ, 800 miles to
Seattle and Salt Lake City. Denver is nearly 1,000 miles. The populated
part of TX is 1,200 or more. IL/WI is 1,900 miles.
That's why it's nice to have 2 different antennas for 80 meters.
IMO, if you can hang a high 80M dipole, the only reason to have another
80M antenna is to put it at 90 degrees to the first one. My experience
and my modeling show that. When working US, I mostly run my dipole
broadside east, and switch to the other one to hear weak US stations
calling me.
Several years ago, I added a reflector to that E-facing dipole to pick
up a few dB on the east coast and EU.
