I don't know if HTTA has any arrival angle data for 6M. It's
predecessor YTAD did not.
Without arrival angle data how would you know some antenna height change
is good, bad or indifferent.
I seem to recall Es prop (at least for 1 hop) is relatively high angle.
If this is what one is after, then lowering rather than raising the
antenna is a better idea. Many 6M ops find 20-25' works pretty well.

I think it will depend on your surrounding terrain. Are you on a hill with a

I have hills NW of me and going from 40 to 50 feet makes a big difference. I
ran the HTTA program on the
CD in the latest ARRL antenna handbook and it was very enlightening to see how
different heights affected
my antenna pattern. I would recommend running HFTA and see what it tells you
for your site. That is the
intended purpose of the program and it works very well.

I am getting ready to put up a Universal Tower 50 foot aluminum tower. I live at
a very high elevation. It will have a 7 element KLM 6 meter beam and a 16LBX for
2 meters. Will I see any difference between 40 foot and 50 foot height? It is
difficult to lower the tower with the trees I have in the yard. Thanks Mike
