Hooking up an HDTV with both cable feed, and digital antenna

by bgaviator2 / May 8, 2010 7:22 AM PDT

I hopefully will be buying an HDTV soon, and we currently have regular cable running to the house, but not with a cable box....just straight cable line. I understand you can pick up over the air HDTV signals now, but we kind of live in a dead I am pretty sure I will need to hook up an outdoor antenna.....How do you go about hooking both the cable feed, as well as the antenna feed to the TV at the same time? Don't most HDTVs only have one coaxial input? If there is a way to run both at the same time, will the TV incorporate both the over the air channels, as well as the cable channels?

you should not have a problem now. Or did your cable company says you have to have your own outdoor antenna for the local channels?

Well, I guess I don't understand how the extra digital channels work....I mean, aren't there channels like 7.1, 7.2, 7.3, etc etc? How do you pick those up? Will those be broadcast through the straight cable line, or can you only get these over the air?

it should have a built-in atsc, qam, tuner; all you have to do is connection the co-ax cable to it and have the tv channels rescan. Then the digital channels should be there. I don't know what cable company you have. I have TWC and on my Panasonic, the digital channels are indicated with a dash (2-1,7-1, 235-10, etc).

Some HDTVs . . .

have two coax inputs: One for the antenna (with a digital tuner) and one for cable. Or get a cable box that has an HDMI output. Connect it to the HDMI input of the TV and the antenna to the coax connection on the TV. This is how mine is hooked up.

I think only LG can do it
by gabereyes / May 10, 2010 3:36 PM PDT

most TV coax inputs have multiple tuners: ATSC for HD Antenna, NTSC for Analog cable and Qam for digital cable.
and the TV will only use one tuner at one time, so to scan for cable channels the tv setting need to be on cable mode, and for antenna channels it will need to be set on antenna or OTA mode.

LG is the only one I know that will do both at the same time, all you have to do is use a cable splitter in the reverse direction, meaning you have cable and antenna going into one wire to the TV set an LG will do a auto scan setup and pickup both local antenna and cable at the same time.
