2. If you're not using over the air channels. Just turn off the power antenna and then the same outside feed (sat) should be feeding to the bedroom coax as well, so the receiver could be located there.
In a nutshell, what I would do.
1. turn off power antenna.
2. Locate receiver in the bedroom with an HDMI multiplexer behind. You would look for one that is powered more than likely due to the length of cables. needs to have ONE in, 3 OUT.
3. You will have to run each wire as a home run. (starts at multiplexer and each TV has a separate HDMI cable feeding it). You could run that below, in cabinets or behind some surface mount wire moulding.
Can someone please help me with the above advice. I like to use a HDMI Multiplexer since I have a Dish Portable Tailgator and I want HDMI signals going to all 3 TV's-Main TV, Bedroom TV, and Outside TV. I will pay to get the wire ran correctly but can I get clarification on what I need to do to be able to use the park cable (outside driver's side rear coaxial near water hookup) and it feed to the Dish Receiver out to the 3 other TV's via HDMI Multiplexer? I would like to know how to configure for both scenarios (if possible) where the Dish Receiver is located EITHER near Main TV over cab near Jumper & Coaxial/Antenna Booster Faceplate OR Dish Receiver located in Bedroom. Not sure where I want to place it yet but would like to know if both options are even doable. Does anyone know of a good brand for the powered Multiplexer (can it be powered usb to TV?)? I need a step by step wiring/connections. I'm so exhausted from trying to figure it out really need some direction. Thanks
