[TowerTalk] Free Standing Tower

[K0FF]

Windmill type towers are great, and Aeromotor made a special one for Ham
use. The one I used was 56 ft tall and 8 feet wide at the base, and all the
pieces bolted together for easy 1 man assembly. The radio version came with
an oversized rotor plate and an oversized top plate. Both these hung over
the edge of the tower by several inches, and a 2" hole was made into each
one to accept a supplied gin pole. Very thoughtful, as well as was the built
in ladder on one leg.
The actual windmill version has a pointy top, and though you could mount an
antenna on it, no provision for a bearing or rotor plate was made.
Radio versions are very difficult to find, I have only seen a few, and they
were both 56 footers. I think they made one bigger size, and that would have
been 70 ', as the "sections" were 14' long each.
A reasonable modern alternative is a Rohn SSV type, but no top plates or
rotor plates are made for them. I have made drawings for constructing same,
and can easily be done by any metal shop. A lot of these are coming out of
commercial service, being replaced by larger, multipurpose towers, so they
can be had at city auctions etc. reasonably.
As always plan for a mast raising winch, no mater which tower you select.
