How will i know if i need a outdoor antenna for hdtv?

When getting HDTV reception over an antenna....?

  • If you can revieve HDTV over an antenna, yet RF cables as far as I know can not support HD resoulution, how do you get HDTV over the air? Do you need a special antenna that has HDTV output? Is there one with an HDMI or Component output?

  • Answer:

    Actually, as long as your have an HD receiver, you don't need any "special" antenna. You can easily use a pair of old rabbit ears and you'll be able to pick up the signal fine. But they DO sell newer antennas that have amplifiers in them so you can pick up a signal even if it's very weak.

HDTV is transmitted over the same frequencies as regular TV, both in the VHF and UHF brand. Any antenna/cable combination that gets good reception on these channels will work for HDTV. Only when the signal is demodulated and decoded is the video bandwidth much greater than standard TV.

There are audio frequencies, video frequencies and radio frequencies, being the highest. HD TV falls into the Video Band,(that means the actual video information is around 10MC), so RF Coaxial cable can surely Handel them. By the way the broadcast channels assigned to digital HDTV do not have enough bandwidth to carry all the video information, it is processed by some trick algorithms, that's why you sometime see anomalies.

A decent cable (RG-6, for example) has adequate bandwith to carry HDTV signals from an antenna. If your TV has a tuner for such (and most HDTV's do), you can just run the RF cable from the rooftop antenna to the set. You don't need a separate box with HDMI output.
