Tod,
The 40m beam shoud be on top.I have a semilair installation and 40-2cd is
playing very well
at 80feet some were.Under is a kt34xa.Don't turn the booms 90 degrees.I
tried but got no differerence
because my kt34xa is a bad performer on 15m.
Also if you load up your tower for lowband, the biggest antenna shoud be on
top. Right ?
Good luck with the combo !!

Subject: [TowerTalk] Who's on top?
I suspect that I could get this answer from a diligent search of the TT
archives, but it is much more fun to get current thinking and experience.
I am planning to install a 40 meter beam (40-2CD) on the same tower and mast
as my triband beam (TH7). Should I place the 40 meter beam over the triband
beam or the other way around. Assume that there will be at least 8 feet of
separation between the two antennas and that the lowest antenna will be no
higher than 72 feet above ground. The antennas will be on a telescoping
tower so the height above ground is another variable (between 32 feet and 72
feet for the lowest antenna).
I have had a suggestion that I turn the booms so that they are 90 degrees to
each other. I can see that will introduce some interesting wind forces on
the tower and the rotator. Anyone have an opinion (or even some experience)
with this concept?
Tod, KØTO
