I finally switched out the SG2100 motor for the heavier STAB HH120.
I had earlier taken down my 90cm dish and replaced it with a 120cm dish. That sucker is heavy.
With the new motor it lifts the dish about a foot higher as the post points up and the dish mount slides over top, rather than hanging from a down pointing motor post.
On both the SG21000 and the new HH120, I had to drill and put set screws in the motor bracket and the motor post/dish clamp, once I had the "zero" aligned. The weight of the dish had a tendency to swing the dish on the posts. (I got a set of new titanium drill bits from a major store but they dulled really fast on the steel in the motor post. An old bit I sharpened, went through it like butter).
It took me three days to get the arc and elevation right. The plasma TV isn't conducive to moving outside. I have a signal meter (about $10) that I used and it was pretty good, though not perfect.
The new STAB motor is slower to turn than the SG2100, but it has the advantage of USALS. That helped. But I don't get 87W any more. Must be the neighbour's trees. I used to get all the way around to 72W with the 90cm dish, when I first put in the system. LPB had some good mystery shows.
I now watch the latest Dr. Who on the internet.
Anyone in the Vancouver, BC area interested in trying out my 90cm dish, it's hanging on the fence, and is just going to waste. And I doubt that I will use the smaller motor again. If you're serious about putting in a satellite system, or just need an upgrade and a rotor, let me know.
