[TowerTalk] 20 METER STACKING DISTANCE

[tgstewart@pepco.com]

It depends on the boom length, but on HF typically you want at least 1/2
wavelength spacing, which will give you reasonable gain and an improved
pattern.  3/4 wave spacing is usually about optimum for gain but the
pattern degrades (compared to 1/2 wave) as you move towards this figure.

Most guys running stacked long-boom 20's use 50 and 100' which is usually
optimum (note this is about 3/4 wavelength spacing).

I AM INSTALLING 2 6ELE 20 YAGIS AND WOULD LIKE TO HERE WHAT YOU HAVE USED
FOR STACKING DISTANCES. BOTH WILL HAVE SEPARATE ROTATORS THE LOWER BEING
A TIC RING.
