Cable coax input on 291RK?
Just picked up our 291RK on Thursday (post with pics coming soon), and I have a question on the coax cable input that the dealer couldn't answer. There's a coax output on the side near the 115v AC power sockets for if you want to set up an outside TV, and the coax input is on the rear by the power input. My question is - there are 2 coax inputs there, and neither is labeled. The antenna is on the roof, and is wired through there, so it's not for that. The coax port for the TV in the living room has two coax sockets which ARE labeled, as antenna and satellite, so I'm assuming the satellite line goes to one of the two ports in the rear...the bedroom has a single unlabeled coax, and I assumed that it was for the second coax port in the back, but with the TV plugged into the coax in the ceiling, I was able to scan and pull down all the digital air channels...so either the signal was strong enough that the TV picked it up without an external antenna, or that coax also goes to the antenna. Can anyone shed some light on this?
