[TenTec] qrp

[Bob McGraw - K4TAX]

Although I'm fortunate to have space to put up antennas and no SD 
restrictions, I've found that "wire in the air" works.  Be it a W shape, a Z 
shape, L shape or an O shape or what ever you can support.  No one said it 
has to be straight, in the clear and up near the clouds.  Mine, 256 ft long 
end to end, center fed with a balanced feed line of the window line material 
from The Wireman, and fed from a home brew real balanced tuner, not a balun 
type.  The wire antennas are 55 ft above ground, supported at the center by 
3 ft steel stand-off arms from the tower.  The ends are ~25 ft above ground 
level.  One is broadside E & W and the other is broadside N & S.  I find 
very little interaction between the two antennas with this arrangement.  At 
the same time, I find that mutual coupling between antennas can be 
problematic.

Now if you have specifics as to direction then of course height and position 
has dramatic effects.  Lower antennas, less than 1/4 wavelength in height do 
produce stronger signals close in.  For DX work, antennas approaching 1/2 
wavelength in height are preferable but won't serve well for close in work.

As to station height, again fortunate that I'm 1850 ft ASL and more 
importantly, some 500 ft above average terrain out to 35 miles.
