I'm going to be adding the SRH2000 Sirius receiver to my setup using the Home Signal Distribution Kit for satellite and cable wiring. The installation instructions are fairly vague, but since my dish is mounted on a mast in the ground, I'm going to use the after multiswitch installation where the combiner is installed after the multiswitch. My question is, do I install the splitter before or after the black power box for the DECA? I have an HR22 receiver. Any info is appreciated!
