dont google FTM get alot of weird stuff whats FTM stand for????Earl Bonovich said:There probably is only 3.... you probably had an installer that decided not to run the 4th line for what ever reason... (I wish it would at least be standard that run all 4 at least to the grounding block).
You should do a search on FTM, so you can see some of the technology that should be comming in early 2007.
That will allow you to run a single line, but still get dual tuner support.
Not sure yet if the FTM is going to allow OTA to be diplexed in yet or not...
But depending on what kind of area you are in, and what frequency your networks are on... you may get away with a "set-top" antenna for your ota
