Install our "PLATE4F" wall plate with 4 'F' connectors at your #1 location. Two cables (LNB1 and LNB2) shown red and yellow come from the dish and connect to the rear of the plate. Two more cables are connected from the remaining sockets at the rear of the plate and extend to your #2 Digibox location.
To use your Digibox at location #2, link both sets of sockets with short connecting leads. To use your Digibox at location #1, remove the "U" connecting leads and connect the Digibox to the incoming dish cable sockets.
