[TenTec] Vertical Antennas (was Radials)

[Carl Moreschi]

The nulls would also be very deep even on 160 as long as all the antennas
and grounds are almost identical.  I am building a receive only 4 square
with 31 foot verticals for 160 and 80.  The information is www.w8ji.com is
priceless and a bible for phased arrays.
