Mark,
I recently took down a R45 tower with a 17' Chromoly mast and a three
element forty on top of the mast. The tower has a thrust bearing at the top
and a Orion rotor below. I stopped by Home Depot and bought three short
pieces of chain and bolts. The three chains were used to keep the mast
"on-center" and were bolted around the mast and around each leg on the
tower. I used a truck scissor jack to jack the mast up out of the rotor.
