I'm going to add a HR54 to my current set up. I have SWM13 LNB out to a SWM 8 way. PI21 into red port on 8 way. 3 HR24's. Solid signal's ULTIMATE GUIDE TO UPGRADING YOUR DIRECTV SYSTEM shows 2 different ways to add the HR54. Option 1: Wire the HR54 to the red port on the 8 way and use it to power the SWM13 LNB Option 2: Add the PI21 between the LNB and the 8 way. LNB line to the PI21 PWR to LNB connection and the Signal to IRD line connection to the top of the 8 way. Are these 2 solutions correct. Any pros or cons. I have access to a PI21 and a PI29, with my set up which power option would you use.
