What is UHF?

Short for ultra -high frequency, UHF is one of the two standard ranges of electromagnetic waves that have been earmarked for the use of broadcasting television in the first half of the twentieth century. In the United States of the Federal Communication Commission, it allocated a specific spectrum of radio waves that would provide access to local television stations. Today, these same belts are still used and also serve several other features. Initially, three specific bands were earmarked for the use of television broadcasts. The range of 54 to 88 megahertz provided room for broadcasting as channels one to six. Frequency of 174 to 216 megahertz channels seven to thirteen. The final UHF frequency band used a frequency of 470 to 890 Megahertz for channels from fourteen to eighty -three.

Over time, UHF broadcast on two lower belts was interrupted, with channels of two to thirteen broadcasts using VHF technology. The UHF Bands for Broader TV continued for several years using the third band. Arrival maSet cable TV and recently using Internet technology have allowed television to continue without necessarily relying on the strict definition of the traditional UHF band.

However, the UHF radio technology is not completely outdated. In fact, UHF radio waves are still active and have a place in today's world. Other communication devices that continue to provide television broadcasting to achieve areas that do not have access to the cable are used by radio waves of this type. As an example, mobile phones often use the limited range of UHF signals in the range of 316 MHz up to 3.16 GHz Portina spectrum.
