I never got a reply from Skyvision to clarify the actuator question (I hate calling tech support - I'd rather do e-mail). So, I'm going to install the 18" actuator and see if it really will move this 12 footer over 120 degrees of the arc and if it'll hold up. Since this Saturday should have decent weather I'll get the reflector assembled and see if any friends are around to get it on the mount.
