I'm embarrassed to ask this question, but will my present analog signal VHF/UHF 18 element Yagi antenna sitting 30 ft above my house work with a Digital signal to a Digital Converter Box? There is also a 22 db pre-amp installed on this antenna. Or, do I have to purchase a so-called digital signal antenna? It seems to me that a signal is a signal and any antenna is capable of receiving it if the antenna is cut/design for that frequency spectrum. What say anyone.

You got my curiousity... From: http://www.dtv.gov/consumercorner.h... Quote Will I need a special antenna to receive DTV over-the-air? In general, dependable reception of over-the-air digital TV programming will require the same type of signal reception equipment that currently works to provide good quality reception of analog TV programming. If you need a roof-top antenna to receive analog TV broadcasts, the same antenna generally will work to receive digital TV broadcasts. You should not have to purchase new antennas that are marketed as “digital ready” or “HD ready.” End of quote Regards, Bryan P.S. Used Google to find this answer using the search "difference between analog and digital antenna"

Thanks Bryan for your reply. I thought I wrote a reply to ignore my question. Wonder what happen to that? In any case, I figured out my problem and decided I would retract what I asked. What I have been finding out lately is that they don't tell you that in order to receive these DTV signals, you need to have a UHF antenna as oppose to a VHF antenna not just plain use your present antenna, without clarifying that it should be of the UHF type. After downloading the DTV listings for stations in the Los Angeles area, is when I noticed that the channels for the new DTV, were above Channel 14. My converter box did not work at first because I had it connected to my VHF Yagi. After hooking it up to my 8 Bay Bow Tie UHF antenna, I started getting many channels for DTV. Instead of telling the public that "yes" you can still use your outside roof mounted antenna, they should specify that it should be a UHF antenna and not a VHF type antenna. All is functioning well now. Thanks again.
