UHF Antenna

A UHF, or Ultra High Frequency, antenna is used as a way of receiving radio or television waves. The UHF band of frequencies falls between 300 MHz and 3GHz. Lower frequencies are considered part of the VHF band, while higher frequencies fall in the SHF and EHF bands. UHF antennas have traditionally been used to watch television stations, specifically those from channel 13 to 69.

The first UHF station was founded in Bridgeport, Connecticut, and it began broadcasting daily in December of 1949. Those who had an UHF antenna were the only people who could watch this broadcast. However, more and more people began purchasing them when, after the dozen VHF band channels had been filled, it became evident that people wanted more television channels. There were also some problems with interference. By the end of the 1940s, there were over 100 VHF stations broadcasting, and some of these stations were located close enough that their broadcasts began to overlap and cause interference. To solve this, the FCC introduced the UHF band of television channels during the 1950s. While many of the first UHF stations to broadcast during this time did not maintain operations for long, the new band of channels was necessary. By 1965, all new television sets featured built-in UHF tuners so that all televisions were capable of receiving these channels.

Of course, to get a clearer picture, many people purchased indoor UHF antenna. These antennas actually look very different from VHF antenna. The VHF antennas were two telescoping metal rods that came out of a base. Termed “rabbit ears” by many, these antennas were long and often presented an eyesore. The UHF antennas, on the other hand, are small metal circles. These antennas are just as capable of receiving signals as the VHF antenna even though they aren’t as tall. Today, many combinations VHF/UHF antenna are available. These antenna features the round UHF antenna situated between the two long telescoping rods of the VHF antenna.

It is also possible to mount a large outdoor UHF antenna on your home or on a metal tower. This type of UHF antenna will get a better signal than an indoor UHF antenna because it is up higher and is larger. However, it can be somewhat expensive, especially if you need to install a metal tower to hold the antenna.

With the conversion to digital television signals, many people have discovered the VHF and UHF antenna are actually still useful. For televisions that are HDTV ready or that have a converter box attached to them, these antennas can pick up digital television signals. This has allowed many people to continue watching television without purchasing cable. Because there is no monthly fee for receiving these signals, the only cost is the cost of a converter or tuner box and, if necessary, the cost of a new UHF antenna.
