I'm just waiting for the lovely lady at Elecraft to send me the gram for the
sub-rx.
In the mean time I'm contemplating the 2nd wire antenna to hoist up for
diversity Rx. My QTH is surrounded by dense trees, cedar 120+ ft tall.
Think planet Endor, ewoks, and pesky storm troopers around every corner.
Now for the 2nd wire antenna, I was envisioning a Beverage because I can run
1000' wire over 7acres in a loop within 30' off the ground without getting
snagged by the branches. Over 30' then I run into problems with very dense
branches acting as barbs in the wrong direction preventing wire from going up.
My main Tx antenna is a wire dipole at 25m cut and somewhat even on each side
for 80-20m work. I'm tempted to take it down and make a new one for 160m +
80m-20m work.
Anyway, the question is: for Diversity Rx, would a 15-25' off the ground
Beverage be suitable? Or, does diversity work best if the polarization is
opposite, -- among the variables involved with wire antennas, what variable to
I look for to increase the benefit of having diversity Rx?
Reply directly and I'll consolidate the responses here on the list.
