My apologies if this has been asked before.
I have an HR44 DVR that has an Ethernet connection to my home LAN and a single coax connection to a SWM8.
I would like to add a "Genie Mini" receiver in another room. There is already a single coax running from that room to the area where the SWM8 is located.
Do I still need a DECA?
How would everything need to be connected?
