Since I already have a 2-high TH-7 stack model, I ran this, and Tom's right
-- 
this setup looks pretty good on both 20 and 15, for TH-7s.  But the funny
thing ... run the same stack with a pair of C-3s, and the 15-meter pattern
is DREADFUL - very little F/B ratio and a lot of wasted power going
straight up.

Can anyone out there suggest why this should be?
