The thread has morphed the globe, and IMHO one person can walk up a 30' tower .
I had a 29' R-25 with 7' 1 1/4 id mast 2mter Hustler G-6 at top a KLM 8
element 440 FM below
plus a BIG Archer TV antenna with a TR44 rotator... up and down no problem.
As for the falling derrick I presently have two 100' R-25 hinged base (
modified from the two bolt ear to a 1/2 SS rod barrel hinge. ) they each
have 46' R-25 Derrick poles... one is 5/5/5 15 meters and other was a 3
element 40 now has XM240 .
