You need a dish pro plus separator at the receiver. It looks like a splitter but it's really a frequency filter made for dish pro plus equipment. You can pick them up for a couple of dollars on ebay. The separator is installed on the two inputs at the receiver then one cable is run from the separator to either #1 or #2 connection on the lnb. You'll have to run check switch on the receiver after it's connected to set it up for the DPP equipment. You'll have to run it again after you connect it back up at home. With DPP equipment you only need one cable for a dual tuner receiver.
