[TowerTalk] How High is enough

[Cqtestk4xs at aol.com]

I've been sitting on the sidelines for this debate and want to  throw my 2 
cents in.
 
As pointed out, all antennas work.  What is your primary  
objective?...working USA?  Working only DX?  Working a 50/50  ratio?
 
For DXing, going higher is usually good, to a point.  Having a  tribander 
at 100 feet is nice.  Been there and done that.  However,  you will find that 
when the band is open for 15 and 10, that will be too  high.  You will find 
you are down compared to guys at 50 to 60  feet.
 
I strongly suggest you take a look at Dean Straw's HFTA program in  the 
ARRL handbook which lets you know the percentage of time the angle of  arrival 
from various parts of the world.  Once you have this info, it will  make 
your decision a little easier.
 
I've used this program to design my last two stations and have not  been 
disappointed.
