VH126N Rotator. Oldy but a goody
I had this rotator on the ground, attached to a secondary mast for a season or two. The KIO hex beam antenna broke my shoes from time of purchase, to the time final installation. (Still not quite final).
Anyway... I believe water infiltrated the rotator, and caused a bit of oxidation at the mating surfaces of the clockwork type gears.
After clean up, lube up, and reinstallation, things seam to be back in order.
Gonna let it run thru the test of winter and see if the system is worth its salt.
