[Elecraft] K3 Diversity Rx and antennas

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.
