My System: 75e-75w C & KU, 36v h-h /36v & diseqc actuators / diseqc -USALS motors / Anlg to HD Channel Masters C120s dishes, stb's inc echo3000, lnbs, meters, custom polar mounts & elevation/incline actuator conversions... |
The basics are just the same as diseqc (not USALS) but you have some playing with the actuator position to get the best arc and miss walls & brackets with the actuator, not just the dish.
Set the elevation of the 'polar mount' to your position, fit the dish on centrally on the polar mount if it is the pole type and does not replace the az/el mount.
Calculate your middle sat and nudge the polar mount dial from zero to plus or minus your offset from that sat with the actuator roughly in the middle of it's movement, leave it there and alter the elevation of the dish and swing the polar mount round until you are on your middle satellite... tighten up both and find all other satellites/ fine tune...
You may want to adjust the actuator position to give more east or west arc....or swap it from left hand to right hand to avoid an obstacle at the back ...
Without the instructions you need to decide the length of actuator to use by measuring the arc movement v the actuator travel needed. |
