I have my CM15A in the office. I do not get enough coverage with it's antenna, so I converted it to coax and installed a Radio Shack antenna in the attic. I have a single run of coax from the structured media box to the office and a couple to the attic, so I used that pair to link the antenna to the CM15A. I was getting a lower than desired boost in signal strength, so I added an amplifier to the run and everything works wonderfully!
Up until now, I've been a DirecTV user. I don't have a TV in the office that's hooked up since I didn't want to pay for a receiver that's never used. So, using the coax run hasn't been an issue. I wanted cable TV when we bought the house, but it wasn't run out our way. Yesterday I found out that a new cable TV company has just extended service to our area and perhaps even across the street, so I'm almost certainly going to switch.
SO... According to the sales rep I spoke to, the service they provide includes: Digital cable, analog cable, cable internet, phone. My question is about using the same line for running my X10 RF antenna on the same line as the digital/analog cable/internet. As far as I know, X10 is in the 310MHz range. According to Wikipedia, there might be interference on channels 38 or 39 if the frequency range is still used.

It also might be possible to move the CM15A to the same area as the structured media box and use a USB->ethernet adapter (already have one and 1 unused connector in the office but never tested how the unit works). Anyone know if I will have interference on either TV or CM15A if I just use a signal combiner? What about potential damage using a signal amplifier?
