[TowerTalk] US Tower 72 ft crank up grinds to a standstill

[Howard]

This thread just refers to a UST 72 crank up.  Specifically, what model 
will not accept the Tailtwister?  I have the HDX 572 and the Tailtwister 
fits fine.


I am now using the Orion 2800.

However, for example, a Hy Gain Tail Twister will not fit and allow full crankup/down of the tower. So, what rotator are you using? - Alan K9MBQ

Verify that the rotor cable and/or rotor body is not protruding such that it fouls the next tower section, and also check the cut-out switches to be sure they are clear.
