Is the Slimline Dish SL3K4R0-01 compatible with a H25-100 receiver? I have one single line coming into house (no splitter of any kind) and a DIRECTV 29-Volt SWM-8/SWM-16/SWM-30 Multiswitch Power Inserter (PI-29Z). I have the SWM connected to the single line coming into the house and the SWM connected to the Receiver but I keep getting error code 775 stating it won't connect to dish. Am I missing some piece of equipment?
