Recently purchase Landmark 2008 - 40' - absolutely no manuals or information on operation of anything. Trying to get TV reception off antenna - Bedroom TV works fine (although I can't figure how it get the signal from the antenna) two coax plugs by TV - one says satellite the other not marked but believe it for cable. Power booster there also. TV in living room not getting signal - dvd plays fine - two coax plugs by TV marked "satellite" one marked "cable" . I see nothing for running coax from TV to the roof antenna. Obvioiusly its somewhere - or a switch to go from cable to tv - any ideas where the antenna coax comes into the coach? Thanks in advance.
