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

[Cqtestk4xs at aol.com]

Although the numbers are over an 11 year range, they do provide an  
average.  I'm a firm believer in playing the averages, since over  the WHOLE course 
of the cycle you will do best designing your  station.
 
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.
