All depends on how far west you want to go
Presently I can sweep from 58 to 148+. I have no need to go beyond 139 or so. I am getting ready to max west travel of the
actuator physically at 139 (probably 141 or so) which will get me a bit farther east.
I have noticed with my dish that the more extreme you get as Will states you "flop" but it also takes less movement to align on a sat. Not sure why but in my "normal" arc I am roughly 9 clicks per sat and out on the ends it drops to around 4.
