The other weekend I had a gentleman install and mount my HD (UHF) antenna on the roof and run a cable into the living room. I had planned to do this myself but for the price it was worth paying the gentleman to do the work. Plus I'm afraid of heights.
My goal in this project was to move my router, cable modem, and VoIP phone unit to the garage. This has allowed me to clean up the area behind my TV in the living room. The "cable guy" ran a separate line for my cable modem to the garage.
He also ran my Ethernet cable to the living room to accommodate my HTPC.
I wired my home phone lines to a block then connected my Power Phone unit to feed the house lines the phone connection.
Once the cables were connected I was able to scan for channels and with my antenna I found 30 channels. I installed a 2 gang electrical box on the wall. The four plugs are just enough for the units plus a feed to strip on my work bench. I mounted the strip in front of my bench which makes it easy and accessible for my power tools, etc.
My ultimate goal is to run my HD antenna into the TV tuner in my HTPC. Then run MythTV. I'll be able to record TV in HD and watch from any PC in the house. Then I'll run the cableTV line into the TV for live TV watching.
