Could you please elaborate on the details of the cabling (and this "node" you refer to), so I better understand?
Right now, we have HDMI (I believe) running from the actual sat dish (on the roof) to a plastic junction box on the exterior of our house. (Is this plastic jucntion box the "node" you're referring to? If not, what is the node?) Then there are 3 coax cables going out from the plastic junction box to....
- one coax goes from the junction box to the 722 in the living room (there's a HD TV#1 connected directly to the 722 via HDMI)
- one coax goes from the junction box to TV#2 in the upstairs bedroom (this has only been receiving an SD signal but we want HD up there now)
- one coax goes from the junction box to the 211k connected to TV#3 in an upstairs office (this is an older, small TV and currently doesn't need HD)
I had been told that coax cable is not capable of transmitting HD programming, and that the coax would need to be replaced with HDMI in order to get HD (at least to TV#2).
Are you saying that the existing coax cables we have - which run from the plastic junction box on the exterior of the house to each room with a TV - would
not need to be replaced with HDMI?
In other words, will coax work to transmit the signal from the plastic junction box to each Dish box (whether that's a Hopper or Joey), in full HD? That is, the only HDMI cabling required would be the short cable to connect each TV directly to it's Hopper/Joey (and the Hopper/Joey can be connected to the "node" via coax)?
The reason I ask (probably obviously) is because I would rather not replace all the coax (which would involve, among other things, drilling multiple new holes through the exterior walls of the house to several rooms, plus running HDMI all around the exterior and though portions of the interior). If the existing coax could be used (and still get good HD) then it would be a much less involved upgrade.
Based on what I've been told and have read elsewhere, I'm guessing that simply re-using all the coax that's already in place is "too good to be true" and ain't gonna work - but I would love to be proved wrong on that.
Thanks for clarification.
