Has any one had problems with this? Whats your general thoughts on this one?

I checked the Eham reviews and I got the impression that people where mixing reviews between two different models of this rotater.

Also I want to know what additional hardware do I need to order when buying one of these.

Do I need a Mast Clamp?

Do I need a Mast adjustment plate?

Do I need a Thrust Bearing?

Any other comments welcome.

I will be using it to turn the following, one 2 Meter (5 element yagi) end mount antenna made by Gulf Antennas with the following specifications.

Specifications:

Boom Length-72"
Boom dia. -1 1/2" diameter

and below that one 6 element end mount UHF yagi.

realistically, you could use a 45 dollar radio shack tv rotor to turn those.

I have tried two of them and they dont move. The gulf alpha antenna is way to much load for them.

You can hear the motor and control box humming under the load. Without the antenna both move fine.

I wonder if that is because the weight is not balanced on the mast?

Your antenna description looks like you need a better rotor. The Yaesu is good. I see what you are saying about confused reviewers.  Do you want to look into a HyGain HAM IV, Alliance HD 73 ??
A Radioshack TV rotor would be stressed with your load and a wind storm or icing.

The G-800SA should come ready to go minus the rotor cable and thrust bearing of course. I guess depending on how the antenna load is distributed on the mast would determine whether you really needed a thrust bearing or not. Probably not with those antennas. I have been using a G-800SA for years and it continues to serve me well today. It has been loaded pretty heavily ever since it has been in operation since the late 90's. It still works like a charm. I have never used a thrust bearing but the load is balanced on the mast. The Rotor will be fine with the weight of those antennas. Those antennas are not heavy. If you are mounting it on a pole you will have to purchase another mast clamp separately.

I would look for a G-800DXA instead of the much older "SA" model.
