[TowerTalk] Using a drill to install (Lay over - Raise) US Tower HDX?

[Tom Anderson]

Brad:

If you'll e-mail Bob, WB5IUU, in Magaolia TX, near
Houston. He can tell you call about the mechanical
winch that used to come with the TriEX W51.
bmennell at comcast.net

He should respond fairly quickly.  I've also cc'ed him
on this e-mail.

Tom, WW5L
