[TowerTalk] Rotator for microwave dishes

[stan]

I am in the midst of planning to mount some microwave dishes on a side
mount
on my main rohn 45 tower (70').   I wlll be using the IIX Equipment LTD
model
RM16 side mount system.

I will start with an array of rear mount yagis for 903 Mhz, with a 2'
radomed
dish for 10 Ghz and a 1' radomed dish for 24 Ghz.

the 1' dish at 24 Ghz has about a 3 degree  1/2 power beamwidth, so I
need
a azimuth rotator with about a 1 degree pointing accuracy and braking
ability
much better than the 6 degree locking steps of a tailtwister or HAM-M

I do not want to dedicate my ORION 2800 and digital controller to this
application,
it will be used later on the multiband EME array.

Are there any other rotators out there suitable for this application ?

wind load is less than 10 ft sq. total
weight is less than 100 lbs.
boom lengths: less than 6 feet


Any help is appreciated.
