[TowerTalk] Optimum yagi stacking distance

[Richard HIll]

W3ZZ has some interesting information in the January QST focused on 50 mHz
and up but perhaps the calculation of effective aperture is relevant to HF?

Pete, N4ZR wrote a great article in the July/August
1996 NCJ title titled, "A Preliminary Look at

That might also provide insight as to specifics.

Hope this helps ...
