What is the difference of HDTV antenna and a DTV antenna?

Q. Which is clearer HDTV antennas or DTV antennas? i have a 1080i flat screen. and want clear tv without cable.

Is there a difference, which is clearer, and which supports HD channels and normal channels both? do they output in 1080i, 720i, or 420p?

A. A TV antenna is designed to receive radio frequencies. They are designed to receive signals either in the VHF (Very High Frequency), UHF (Ultra High Frequency) range or both. A TV antenna does not know nor care if the signal has been modulated with an analog or digital signal. A TV antenna does not care if the signal resolution is 480 (SD) or 720/1080 (HD). It only matters to an antenna the frequency of the signals it is designed to receive.

This is why there is no such thing as a Digital Antenna, a HDTV antenna or a DTV antenna. There are UHF, VHF or UHF & VHF TV antennas. There are directional antennas and non-directional antennas. There are many tpes of antennas.

If you want the strongest signal strength for your HDTV, then use the web site http://www.antennaweb.org This web site will provide you with a list of channels you can reasonably expect to receive at your specific location, what type of antenna will work best at your location, what direction to point that antenna and if you need amplification on your antenna.

A. There is no difference, it is all marketing names for antennas to make them sound new and exiting.

None output any particular resolution better than the other.

Antennas will vary how they only receive the over all signal, which is mostly an all or nothing deal.


Will an hdtv antenna work on a non hdtv?
Q. I have an old Sony Wega tv that is not an HDTV. I want to buy an hdtv antenna and was wondering if it will pickup any channels. Also, what is the purpose of a digital converter? Will a hdtv antenna connect to a digital converter and make the picture of my non hdtv into hd quality?

A. >Will an hdtv antenna work on a non hdtv?

All TV antennas are "HDTV" antennas, even 30 year old ones.

Antenna requirements depend on your location. Having "HDTV" slapped on the box tells you nothing about whether an antenna is suitable for your location.

>Also, what is the purpose of a digital converter?

A DTV converter takes digital broadcast signals and converts one of them to the old analog type so your old TV can understand it. As far as your TV is concerned, the output of the converter is just like an old analog TV station on channel 3 or 4.

>Will a hdtv antenna connect to a digital converter and make the picture of my non hdtv into hd quality?

The converter boxes only output non-HD quality. But if the TV station is putting out a good quality signal, that's about DVD quality.

>Sony Wega tv

I assume that it has a S-video input. If you get a converter like the Channel Master CM-7000 with a S-video output, you can get a little more picture quality out of the TV by using a S-video cable.
