Be sure that you check the dish for damage or warping during shipping before mounting onto the elevation bracket. FSS signals are much weaker than the DBS satellites. I prefer using a glass table, if available, and lay the dish face down. Observe to make sure that the edge of the dish is laying perfectly flat with absolutely no gap. If not, pick the dish up by the high edges like a steering wheel and lightly thrust the dish away from you while flexing your wrist. Lay the dish back down to confirm that all edges are laying flat. If not, repeat.....
Use the included Tripod support legs if using the Universal Roof/Wall mounting post. If not, you are just asking for a warranty service call when the winter winds load up on the 36" dish. You will really like the included spirit bubble level and self-leveling post. You don't even need to mount the foot straight to plumb the post!
Be sure that the LNBF rotation (skew) is set. Standing in front of the dish looking into the reflector, the LNBF will be rotated counter clockwise. If not set correctly, you might not get a signal quality reading from the receiver.
If you have any problems locating the satellite use a DirecTV LNBF and a Signal Identifying meter like a Lacuna, SatHawk, Birdog, etc. or a DirecTV receiver, place the DirecTV LNBF in the LNBF clamp and locate DirecTV 101W. Swap back to the included linear LNBF and connect to the system's receiver. Place the receiver on 3ABN (strongest Transponder) and fine tune the dish aiming then the LNBF rotation. Next go to the HOPE Channel and further fine tune on the weaker channel.
If the system includes the Fortec Mercury II receiver, be sure to follow the instructions and activate the preloaded channels before starting the install.
