I am still undecided on getting a Wally or take the Hopper 3 out of the house for the motorhome. One thing I have not found is a schematic for the Wally to see how many cables is needed and what type of LNB is used. I only have one cable for the tripod setup and only one for the Trav'ler through the roof. I have found numerous different schematics for the Hopper 3, but none for the Wally. If I get the Wally I will be getting an external hard drive plus the dual OTA adapter for recording. There will only be one receiver used in the motorhome. I have a HDMI splitter setup that sends the signals to all three of my TV's.
