[TowerTalk] 4 square arrays

[n4kg@juno.com]

As others have also indicated, current flow into a severly tapered
element is minimal, meaning that a thin tube at the end of a thick
element provides little additional loading.  You need a capacity hat
or fat element to effectively extend a conductor.

A 90 ft tower and 3L20 makes a nice 160M top loaded vertical.
How about 4 towers, plus 4 - 3L20's aimed in 4 directions, no rotors?
Gives you an efficient 160M radiator plus instant switching for world 
wide coverage when 20M is open to all continents late at night during 
high sunspot condx.

Some 40 ft towers and 10 or 15M beams would do nicely on 80M.
