Hi Stan,
Yes of course you are right and so too was VE7RF to whom I apologize
with a red face. The comment though about also wanting to use the Beverage
for 80/40 though is still valid; I hope.

Doug,
Thanks for the contact in 160m Contest. I was ZF2DX that weekend.
.05 = 1/20 but VE7RF, for some reason, calculated a half wavelength instead
of a wavelength and then divided by 10 instead of 20, so his end number is
correct. Whether .05 wavelength height works well or not, for practicality
I can't imagine anyone putting up a Beverage that is 500-1000 feet long and
having it up 25 feet or so when it is likely to work better at a practical
height of 6-8 feet.
73...Stan, K5GO
