Gary, I have seen 2 different mounts like you describe. One uses two
verticals spaced about 2 feet of the rail material used in garage door
openers. The trolley has wheels designed to travel inside the rails. The
second uses 2 steel cables spaced the same with turnbuckles to keep them
taut. The trolley is a plate or frame with vertical pipes sliding up and
down on the cables. Both systems would use horizontal angles at top and
bottom bolted to the pole. I think these angles would need struts to handle
the twisting forces the beam and rotator put on the pole.

Subject: [TowerTalk] Pole Mount for Beam Antenna
Hello,
Does anyone have any suggestions of what to use to mount a beam on a
wooden pole where you can raise and lower the antenna? I saw something
years ago which was some type of rail arrangement on each side of a pole
that held a platform that held the rotor and thrust bearing. It was
raised and lowered using a boat winch if I remember correctly.
Any ideas will be appreciated.
Thanks & 73,
Garry - WR4R
