[TowerTalk] Tower Loading

[gbay]

I have a 72 foot motorized tower, TX-472MDP, with a TH-11DX on top of it.  I
am attempting to load it with a gamma match for 160 per the books.
Unfortunately, when I dip it, the frequency is about 6.5 Mhz.  Thus, it
would appear that the TH-11DX is not providing any top hat loading.  I
recognize that the driven elements are insulated and thus, presumably,
provide no effect.  However, I had hoped that the boom with the directors
and reflectors would provide adequate loading.

Has anyone tried to load a tower with a TH-11DX on top?  If so, with what
results?  Has anyone tried to model this setup?  I'm pretty mystified as to
what is going on so any help would surely be appreciated.

73 and happy Thanksgiving de Gerry, W1XY
