The really big DXers have more than 1 beam on the tower and they feed them
stacked or singly to favorer the distance wish to work.
I have a height limit here of 40' and my antenna works OK, 271 confirmed,
but I wish it could be another 10' higher. I think it would work a bit
better. Remember if SWR and SWR bandwidth is important to you, then height
above ground is important. Check and see if the antenna your using specifies
a minimum height, mine did.

Depends on what you want to do on 20, Bill. "Normal" 20M ops can get away
with 50-70 ft.; DXers usually demand 70 ft. minimum. Now, here's the
kicker: it's not 70 ft. above the earth; it's 70 ft. above *ground
reflection*. Where's your water table? How about local rooftops, and
other
ground clutter? Aw, heck, just put it up 100 ft., and you won't have to
worry about it!!
