[TowerTalk] vertical distance

[Jon Zaimes, AA1K]

I have an 80 meter broadside-end fire array of four 1/4 wave wire verticals. Three are hung from trees and one is hung from a 100-ft Rohn 25 tower, spaced out about three feet. The tower holds a small stack of 15m beams. The array is nested within a similar array for 160 meters and each 80m element taps into a single radial of the 160 meter on-ground radial system.
Analyzer readings when I installed the 80m elements were as they should be. Had they not been, I would have looked at detuning the tower (or any of the 7 other towers 50-200 feet away). I found no interaction with trees either.
The 80 and 160 arrays work very nicely.


73/Jon
