Help would be appreciated.... I am currently going through a fairly extensive renovation leaving me with out HD for 3 months....I want to run a new line into the bedroom, so at least we can watch in there...The dish is probably 75 feet from the room, is that too far? Secondly, does the run from the dish have to be RG-6? I tried running going through the lines that currently feed the older receivers, but I never get a signal. Thanks!
