[TowerTalk] Stacking Distances

[w9ac@arrl.net (Paul Christensen, Esq.)]

What is the most common stacking distance for two Yagi arrays currently in
use at the premier contest stations?  Full-wave spacing would produce the
most forward gain, but I continue to see references to 5/8-wave spacing.

Question:  Is 5/8-wave used as a compromise spread in that the difference
between 1 w.l. and 5/8 w.l. is relatively small but closer than 5/8 w.l.
produces quickly diminishing forward gain?  Or, is there a benefit of 5/8
w.l. that minimizes an unwanted lobe?
