[TowerTalk] Lift Mast to Replace Rotator

[Robert Harmon]

I am getting ready to install a new Alpha Spid rotator and called them with this question.  The Alpha Spids do not require any vertical weight.  They will run fine
without it.  

I don't know of a rotator that requires an axial load.  The Hy Gain's do not.
