[TowerTalk] FWD: Raising and lowering the mast

[Jim Idelson]

Anybody have a good solution for raising and lowering a long mast in a Rohn 25 
tower? The mast is 1/4" chromoly 24 feet long. The rotor is a TailTwister on a 
rotor shelf 8 feet down from the top of the tower. A TB-3 thrust bearing is 
mounted on a rotor shelf immediately above the rotor. Another TB-3 is located 
on the flat-top. 16 feet of mast extends above the top of the tower.

Objective is for one man to be able to easily lower and raise the mast about 10 
feet in order to install and maintain HF antennas anywhere on the mast.

73!
