2 things from what I've read you aren't supposed to hook up an hr20-100 to deca without the Internet hooked up. Is this true, will it work properly or not. 2nd thing is they ran out of regular decas and our sending us out with broadband decas. They don't have a coax pass thru like a regular deca. What would the best way to hook up one of those behind an hr20-100 instead of a regular deca. We were told to put a 4 way behind it . 1 to broadband deca , 1 to sat 1, and one to sat 2 .
