I am "considering" the possibility of running 105 feet of pipe extending the 
existing mast to near ground level and mounting the rotator at that location.  
The antenna is 20M5L48.  I have to take the rotator down because of a 
maintenance issue anyway and thought that in the long run it might be nice to 
have the rotator low to the ground.  

The plan would be to use 1.5" Schedule 40 pipe (1.90" OD), leave the two thrust 
bearings that are located at the top of the tower and down about 6 foot, add 
another thrust bearing about 10 feet above the rotator and have about 3 or 4 
other brackets with UV inhibited PVC bearings to center the mast from about 20 
feet to about 110 feet.   

If any of you have done something similar, I would appreciate knowing the pros 
and cons of such a plan.

Thanks...Stan, K5GO
