Hi John,

I had to do some tests of different antennas for a manufacturer, and 
I bought a Butternut. It was one the best performer of the group 
tested.

If you elevate the antenna that high, you can do without an extensive 
ground system. Four radials on each band should be plenty at that 
height.

I used a 14AVQ or something (forgot now) at 160 ft, with a five 
element 20 meter monoband beam as a counterpoise. It worked killer on 
40 up, and was only about eight or ten dB down from the 5 element 
antenna.  

I used the vertical as my main TX antenna, and listened on the yagi. 
That reduced QRM substantially, by keeping the frequency clear of USA 
to USA contacts.
