[TenTec] Vertical Antennas (was Radials)

[JAMES HANLON]

Guys,

Does anyone here have any experienced with vertical phased arrays?  In 
particular, I would be interested in the equilateral triangle configuration. 
Per Capt Paul H Lee, two vertical elements with a spacing of 210 degrees and 
with equal, in-phase currents have a figure-8 pattern with a gain of 5.2 dB. 
(I think his reference antenna for 0 dB is a single vertical element of the 
same height, but I would have to do some additional work to check that.) 
Three vertical antennas can be used, two at a time, to provide coverage and 
gain over a 360 degree pattern.
