UHF Television Broadcasts in High Definition

Saturday, November 03, 2007

Since the Second World War, television broadcasting has grown tremendously. The Federal Communication Commission came out with 12 “very high frequency” (VHF) channels numbered 2 to 13 and thereafter it has launched “ultra high frequency” (UHF) channels numbered 14 to 83. In the early 1980s, cellular telephone frequencies existed with channels 70 to 83. In coming times, in view of rapid growth in portable communication services there was a possibility of coming out with channels 52 to 69. There was thus the need for having a UHF antenna to accommodate these 18 channels.

These 18 channels would have the High Definition TV broadcasting standards which could broadcast up to 6 digital channels. Now, about 90% of the high definition broadcasts are under the UHF band. The most remarkable feature about the UHF band is its exceptional picture and sound quality. Moreover, digital broadcasting does not create channel interference when working on spacing of TV channels.

UHF HDTV antenna is necessary for good UHF HDTV reception that is immune to certain types of interference. Improving UHF TV reception is a do-it-yourself kind of job that involves installation of an UHF antenna. When the viewer wants good TV reception and does not want to be troubled by external interference, UHF antenna is a sure way.
