DVB-T antenna - Fact or Fiction

"Buyer Beware" We've all heard a thousand times, but many consumers continue to purchase products with false or misleading information. An example is HDTV antennas. Allows you to separate fact from fiction.

FICTION, special antennas are required to receive the new HDTV / digital signal processing.

HDTV

IN FACT, HDTV and will air on many of the same frequency channel for traditional analog television broadcastYears.

FICTION; All HDTV / Digital signals are transmitted on the (14-69) UHF frequency band.

DONE; Almost all television markets in the United States have at least one or more VHF (2-13) and UHF (14-69) HDTV channels.

FICTION, I have my current TV antenna to receive HDTV to replace.

In fact, if the antenna is the current TV signals VHF (Ch.2-13) and UHF (Ch.14-69) and can be kept in perfect condition, it is unlikely that aThe changes will be needed.

Because of widespread misunderstanding, many people buy two TV antennas. The first antenna will be purchased as an HDTV antenna. This antenna is a UHF TV antenna. The well-meaning dealer who sold the idea that the antenna would transmit all HDTV / digital signals in the UHF band.

I think for the most part, this is an honest mistake. All stations are required to pass on their traditional analog signal until February 2009. A At the same time, broadcast their new HDTV signal. Omitted because of space limitations for the channel, the most HDTV channels are temporarily assigned to UHF channels and will be permanently assigned in February 2009. At this time many of the HD channels currently broadcast on the UHF (Ch.14-69) is to return to the VHF (Ch.2-13) frequency.

The fact of the matter is, there is no difference between a traditional TV antenna and a> HDTV antenna. Even if some people want you to think that this is simply not true.

Used when choosing your HDTV antenna, the same guidelines for the selection of a traditional antenna. Consider the quality of the antenna, the size, scope and amount of money you want and in most cases, be sure it's VHF / UHF capable. Remember, if it sounds too good to be true, it probably is.
