Whitch motor

[chifut]

E.B. Are you use DG 9120b motor? How much degree are the C/KU lnbs apart on the picture ?

[el bandido]

I have a DG380 and a 9120 with the larger tube on it. The 9120 and the 380 travel too far in the arc to support a 1.2 meter dish. They get in a bind at the far ends because of the weight of the dish and their higher gear ratio.
The 9120 and the 380 are much faster than the Stab HH120 but they cannot handle the weight like the Stab can.

Spacing is about 4 degrees with the lnbs side buy side as shown in the picture.
Some c band transponders were stronger with a scalar ring installed, but some transponders seemed stronger without the scalar. I spent the better part of 6 months running different c/ku combinations on the 1.2 meter dish.
