Topband: Some Success

[Pete Smith]

I would try to find that sweet spot first, because if you're like me, 
you never will.  I have stacked tribanders, a 2-el 40-meter beam and an 
80 meter lazy-v array all on one tower.  I modeled the thing and found 
where (supposedly) the 50-ohm point would be.  After about 5 trips up 
and down the tower, without finding anything even remotely close to 50 
ohms over a +/- 15 foot range, I gave up and just left the omega match 
in place.
