Hi John;
I am using an AR-303 rotator with a small resonant loop, and have had this mounted outdoors for about 3 years now.? This appears to be identical to the RS unit.? I have had no problems with the rotator head itself, and it has worked without problems here in Chicago in temps down to -20F.? I do not use it for DFing or signal nulling, but tweak it occasionally to depress local noise as heard on the loop.
The control itself has its issues, and I have had to open it a couple of times to find and remove pieces of broken plastic which jammed it up.? This appears to be a common problem, but none of the problems I have had have been game enders.
For $50 this is a good deal and should work fine, especially for an indoor siting.
