[TowerTalk] Triband Stacking Distance or antenna height?

[john at kk9a.com]

Did you just feed upper and lower on 20m? Unless the undriven antenna causes
some bad interaction, using all three on 10m and 15m and skipping the middle
on 20m could be a good triband stacking solution!

I've had lots of experience stacking antennas....from monobanders,  to 
duobanders for WARC to tribanders.
 
I wouldn't think twice about putting up a stack for any band, if  money and 
labor was not an issue.  I'd rather have two three element Yagis  stacked 
than on e 6 el at the top height.  Why?  Flexibility is the  answer, as well

as maintenance.
 
Triband stacks?  I had them out at KH6 at around 90/60/30  (KT36XA).  Yes, 
the middle one was probably not really a big  contributor for gain on 20, 
but the signal brought endless piles of EU and  NA on that band, since the
90 
over 30 was still in effect.  15 and 10  were where they really shined.  
Granted I was on a nice big hill, but I  could definitely tell how much
better 
the stack worked rather than just the top  antenna.  I also have the same 
stack at my place now and although it is  down a little from the 4 high 
monoband stacks on 10, 15 and 20, it still is a  very able performer.
 
If the sale of my house goes through the triband stack will be  employed at 
my new QTH in the Caribbean.
