I am looking for something that does not seem to exist!An amplifier/transmitter for dtv that connects to the coaxial wall socket from the roof antenna and resends the boosted signal throughout the house without the inconvenience of layingout much cable & crawling through the roof space to do so.Running a set=top box is the usual solution offered & completely miisses the point-you can only use one channel & need an infra-red range extender or some-such-again missing the point-I just want free-to-air dtv on my tv in whatever room I'm in without the cable-It's not my house so changes are not necessarily possible.I can't be the only person who wants this thing but no-one seems to make them!!Kere's hoping someone somewhere knows something helpful!
