John, are you currently using a TV transmitter to send SA IPTV to additional TVs?
If you had Sky Angel satellite, then you already have coax cable running around the house. All you need is an RF modulator (costs $10.00 at Family Dollar), and a good quality splitter, and you can WATCH Sky Angel all over the house.
Here's my setup:
I have "limited basic" cable TV for the local channels. This goes to every TV in the house.
I have one IPTV box in the den. There's no point in trying to share that one, because the kids are always watching it.
I have another IPTV box in the master bedroom. I connected an RF-Modulator to that IPTV box, and then a coax splitter to the rf-modulator. I have Sky Angel connected to all of the other TVs in the house, as well as the VCR in the master bedroom, by using the coax cable.
At each of the "outlying" TVs hooked to the Sky Angel coax, I put an "antenna/cable" switch, so I can switch between cable and Sky Angel. (If you don't put a switch, then cable won't work on a TV whenever there is a Sky Angel signal present on the coax. Not sure why.)
I then can watch Sky Angel on any TV. If it is any TV other than the den or the master bedroom, I have to tune it in in the bedroom. Therefore, I'm looking into getting a remote extender.
