I recently moved into a new home, and have a question regarding an HDTV hookup. While the house was being built, I planned for mounting an HDTV above the fireplace / mantel, and had a coax cable and a power outlet pre-wired in the correct location. My initial plan was to just put the cable box on the mantel, and run the output signal from the cable box to the TV.
During our "pre-drywall walk-through" the builder encouraged us to go with their "plasma TV package" which we did. This setup essentially transmits component / composite / stereo sound from "point a" in the corner of the room to "point b" above the fireplace. The connectors are wired with cat5 cable. Up to this point, I have no questions.
Unfortunately, when the builder convinced us to go with their option, they neglected to tell us that this upgrade did not come with a coax run as well. Thus, while I can move an HD signal from the corner of the room over component cables, I have nothing to hook the cable box up to.
Fortunately, when the video option was changed half way through, it appears that the coax was left in place behind the wall (though the f connector was cut off). This cable terminates at "point b" above the fireplace. I'm assuming this cable is still home run to the distribution point, and will verify this before undergoing any project. I'm also fortunate that when the HD package was wired, they included an extra cat5 cable from point a in the corner of the room to point b above the fireplace.
So my question is, can I get a video balun such as the one below, connect the coax at point b to to the cat5 at point b (with all this hidden behind the wall), then convert it back to coax at point a, terminating in a standard coax jack? If I do this, will the cable box be able to receive a full signal (I'm using Verizon FiOS in Howard County, MD)?
Thanks very much for any comment or suggestions.http://www.hdtvsupply.com/mux-500302.html
