I have a coax cable running from the back of my vu box(with rf mod) up to my roof space to my amplifier box. I do not get my terrestrial tv channels as I am told that I need to have a second cable running from the rf modulator box up to my roof space amp box. I cannot get a second cable up there and have been told one cable is fine if I use a diplexer.
Never heard of this, anybody know about this...?
