Topband: Location of WF RX Antenna. Need Expert Advice

[Steve Maki]

I've just recently been reading up on Waller Flags, and am certainly no 
expert, but my impression so far is that an HWF (horizontally polarized 
flag), mounted up in the air on a tower, should be less affected by tall 
vertical thingies in the area; and less prone to local noise in the area 
which is normally vertically polarized, all of which is a major 
attraction of the antenna. So if your nearby horizontal items are not 
long ones in terms of wavelength on the frequencies of interest using 
the flag, I wouldn't expect a problem.

If your plan is a vertically polarized flag, than ignore the previous 
comments.
