Over-the-air (OTA) HDTV becomes more and more popular. For someone who is used to noisy analog TV pictures, it is hard to believe how amazing a quality of HDTV broadcasts can be. In fact, HDTV channels received over the air free of charge often have better quality than the same channels received through a paid satellite HDTV subscription. All you need to enjoy OTA HDTV is a HD television with a built-in HDTV tuner and an HDTV antenna.

"Acacia is rapidly becoming the leader in technology licensing and we continue to grow our base of future revenues by adding new patent portfolios," concluded Mr. Ryan.Huh? Which kind of antenna?! If you have Ph.D in Electrical Engineering and have never heard about the antenna type called "HDTV antenna", it's not because you were a bad student. HDTV antenna has nothing to do with physics and engineering. It was invented in marketing departments. Marketing found an effective trick to boost TV antenna sales. HDTV is a hot thing these days. Call essentially the same device HDTV antenna, and it sells better. It makes people to believe they must buy an HDTV model or HDTV optimized antenna to watch HDTV broadcasts. This is very far from truth.Information about Acacia Research Corporation and its subsidiaries is available at www.acaciaresearchgroup.com and www.acaciaresearch.com.Well, the antenna bandwidth and frequency response are not the only parameters that are important for clear TV reception. An antenna has other important electrical and spatial properties, such as antenna gain (directivity) and high front-to-back (F/B) ratio. One might assume that an HDTV antenna should be more powerful in terms of F/B and gain parameters. Does HDTV reception impose more stringent requirements on antenna gain and F/B ratio?IRVINE, Calif., July 7, 2011 /PRNewswire/ -- AmTRAN Video Corporation (AVC), a subsidiary of AmTRAN Technology Co., Ltd. (AmTRAN), a top manufacturer of flat-panel TVs globally, today announced the launch of a new JVC high-definition television (HDTV) line for the North America market. The new BlackCrystal(TM) series of JVC HDTVs are the first products to be made available under a licensing agreement announced in October 2010 between AmTRAN and Victor Company of Japan, Limited (JVC), an operating company of JVC KENWOOD Holdings, Inc. (JVC Kenwood.)
There is nothing specific about a TV antenna that is used to receive HDTV. When choosing an HDTV antenna, check the really important parameters such as directivity, gain, F/B ratio. These specifications are important for reception of both, digital and analog broadcasts. The HDTV optimization is probably the least important factor you should take into account.
