[TowerTalk] ProSisTel PST110D-Pro Rotator

[Patrick Greenlee]

Kurt Andress, K7NV, modifies prop pitch motors for use as antenna 
rotators.  In my opinion he does excellent work of the highest 
standards.  His "rotators" are very stout.

Go here and get his "story" ==> http://www.k7nv.com/proppitch/

Get the right size from him and color the problem done.

I am in "Oklahoma, where the wind comes sweeping down the plain..." I 
have a SteppIR DB42 that weighs 250 lbs and is NOT aerodynamically 
balanced nor is it balanced weight wise.  I researched rotators and 
found some that  might last.  I also found Kurt's re-purposed prop pitch 
motors and ordered one.  He did not try to upsell me.  He recommended 
his smaller unit as more than adequate for my needs. Green Heron has a 
version of their fine controller expressly for these converted prop 
pitch motors.

I advise you toi at least talk to Kurt before you decide what to buy.

I'm not affiliated in any way with Kurt except being a customer.  I like 
to think I can recognize quality in products and persons and do in both 
categories in this instance.
