The RD-46 should work OK. The "Switch" is used if using a dish with more than one LNB and since this model of dish has only one, no switch is required, so "None" is
a normal reading in this case. The 3 Dish satellites are at 110, 119 & 129 degrees with the main ones being 110 & 119. You can only pick up one at a time and therefore only view the channels that one is transmitting. If you have a smart phone or tablet, I have found using an app like SatFinder very helpful with aiming the Dish. Also, once you know about where the satellite is positioned, you will see if trees or tree branches could be in the way and blocking the signal.
