Not to dispute David, but for a regular residential install, you might want to first try mounting the receiver with the M1.
I have the Receiver mounted in the same box as the M1, in a wiring closet with a 200 amp panel, 1 subpanel, two video amplifiers, my Homeseer PC, an Ocelot, what looks to be about a mile of wiring, AND the incoming water line for the house. Oh, yeah - and it's in the far corner of the basement!
Works fine all the way to the other far corner of the second story of the house, through a layer of Mexican tile and a bunch of granite.
This Caddx stuff is incredible...
