Hi Alan

All very true.

I had a g1000 to turn my TH-5.  with time, mechanical wear happened, to the
extent that even in light winds it would "knock" while in the resting
position.

Hello Bob, 

The Yaesu G800DXA is a very small rotor.  I would not use it on any yagi
with a boom of over 15 feet, and a weight of in excess of maybe 75 pounds.
Remember that Yaesu rotors do not have a break of any kind.  Yaesu rotors
use a jack screw to turn the antenna, and since you can't turn a work
drive/jack screw backwards, the mechanism itself acts as a brake.  If you
put too much of a load on a rotor of this type, you run the risk of ripping
the guts out of the rotor pronto.
I suggest that you buy at least the G1000 which is heavier than the G800.  I
currently use the Yaesu G2800DXA to turn my DB-36, Yaesu's largest rotor,
and mine broke Friday morning and will likely have to be scrapped.

Good luck.

It's considered a medium duty rotor. I plan to use mine to turn 27 
pounds of fiberglass on a push up mast.    I think if I were doing your 
project,   I would go a lot bigger.    More money, but more piece of mind.
