1.Truly passive and non-transmitting
2. Only coax is used. The remotes can use both IR or RF so make sure the tech knows that you want IR and if you want an internet connection for ON Demand tell the tech to use the wired DECA BB.
3.Both Genies are SWM (Single wire multiswitch) only, other receivers can use either the 2 coax system or the SWM, but the SWM is easier to install.
