Topband: Beverage versus K9AY versus short verticals

I use a 3ft high 350ft E-W beverage only 20ft behind my shunt fed 160m
vertical and in practice it works well both in real terms and in comparison
with 650ft beverages 1000ft out in clear.
Obviously the longer beverages are better, but only by up to an S point or
so in s/n in their optimum directions and condx, normally less.
A K9AY is likely to have more interaction with your tx vertical, but then if
you detune your vertical phased K9AYs should work well (in theory better
than the beverage) also. Tom W8JI's web page has very useful data for
comparing these antennas.
