Did some searching but couldn't find an exact answer to this. I'm ditching ATT for many reasons and want to try Comcast. I have two rooms with Cat5 connections but no RG6 connections.The Cat5 will be used exclusively for the A/V cable signal. Can I use a Balun from the incoming comcast RG6 to convert the signal for use over the Cat5 to each of these two rooms, then convert it back to RG6 to input it to the cable box and have it work? This will be HDTV with premium channels. Didn't know if the Balun would cause a problem with the encoding of the premium channels.
If this can be done, will there be a picture quality degradation or other down-sides to this I should be aware of?
I don't think this will work. If you could find a balun that would match RG6 to CAT 5 the leakage from the CAT 5 would be so high the cable company would be required by FCC rules to disconnect you.
