Al:
I have been using the ORION 2800 AC rotator for many years, and had to replace
the controller (M SQ) as it failed as it had often in the past. I am currently
using the Green Heron RT-21 Controller as it was recommended as my solution,
and I have been very pleased with it. Very simple to configure it.
I have no knowledge of the ARCO controller, but plan to stick with my Green
Heron Controller. For me, it has been the right choice. I am turning a HyGain
TH-11, a 5 el 6M beam, and a Cushcraft 2 el 40M beam with it. Bought it used
about 5 years ago, and it has been doing a great job since then. Found the used
one on eHam.net. - John Owens - N7TK
