[TowerTalk] How High is enough...(HFTA) now

[john at kk9a.com]

A lot can be done with two tribanders.  Besides changing the radiation
angle you can also beam in two directions which is very useful if you
contest.

I had BOP capabilities with my 40m beams. I thought that it would be great
for the one domestic contest (November Sweepstakes)that I operate however
I have never found this option useful. I have never tried it on other
bands.

Having the ability to change that optimal angle is a big  advantage.
Although my stacks are all very high, the ability to BIP/BOP  them allows
me to
accommodate the higher angles that are not covered by the  higher antennas.

Of course, if you don't have stacks, you can do the same sort of  thing
with a second antenna at 50 feet.  Not only does this allow a change  of
angle,
but with this proper phasing apparatus you now have a second  antenna...but
also a stack that can be switched in and out of phase.

That would be my recommendation.
