[TowerTalk] Beverage Antenna

[john at kk9a.com]

What happens if the Beverage happens to be parallel to a steel fence? 
Perhaps 10-20' away.

Anecdotal reports over the years (~ 30?) of Beverage antennas over
an existing conductive wire/fence indicates that performance lags
that over moderate earth.  The degradation comes from two apparent
modes: 1) the (typically larger) fence picks up noise and couples it
to the Beverage and 2) the the conductive nature of the fence upsets
the velocity factor (wave tilt) resulting in a shorter effective
length with lower signal strengths and broader patterns.
