Apologize up front for my lack of techno geek definitions, but will try to explain the best I can. I just moved in to a new house with a cable connection (coax) in the living room. I can take a coax cable from the outlet and connect it directly to a LED flat screen TV and it works fine... My wife wants the TV placed on the other side of the room. There is no way to run a coax cable across the room. There has to be something that will send the signal wirelessly across the room. When I look on the internet, it appears possible with RCA or HDMI connectors, I saw one device that uses coax cable as input to the transmitter from AITech (under Wireless Cable TV) but it doesn't support HD.
There has to be other options take a coax connection and move it wirelessly across a room and retain HD quality.
Appreciate any and all thoughts/input.
