[Antennas] Butternut Vertical

[CBoone@Earthlink.Net]

All ground mounted verticals must have radials....BUT a vertical
mounted at or >.07wl above ground will work 99% as well with only
FOUR radials that are AT LEAST 1/4wl long at lowest freq...
This was stated on a web site by W4RNL and I have confirmed it at home
with a vertical mounted 20ft off the ground and it only has 4 60ft 
radials...works great on 80-10 and bandwidth/resonance is EXACTLY as it
was on the ground with 32 radials...

Also BC stations with AM sticks on top of bldgs have reported the
same thing...though the antenna has few radials there, being above
earth ground allows it to work well with only a min compliment of
radials...(one AM station here in Houston had that with its antenna
atop the old Rice Hotel!)
