What is a UHF antenna?

An ultra high frequency antenna or UHF is a type of antenna that is structured to pick up broadcast signals from channels that transmit on ultra high frequency waves. In terms of actual channel identification, this involves every television broadcast channel between the range 14-83. 

In many cases, one antenna is configured to receive both UHF and very high frequencies from the VHF signal, but it is possible to buy antennas inside and outside which only accept UHF signals.

In many areas, most television broadcasts involve stations that transmit on UHF bandwidth. This means that anyone who wants to receive their signal over the air and not through cable or satellite services will need an antenna for optimal reception. 

There are several types of UHF antennas that are designed for this purpose ranging from compact models intended for indoor use only, and more robust models that are installed in the attic or outside. Generally, antennas that are installed inside will have about half the size of the outside model, which makes this smaller UHF antenna more suitable for people who live in cities and more large outdoor antenna models are more effective for those who live in remote area.

One of the benefits of UHF antennas is that this solution is much cheaper than UHF / VHF models. This is because the hardware required to receive VHF signals is somewhat more complicated and significantly increases the device costs. Assuming that most broadcast stations in the area are UHF, homeowners can do that option well by using one cheaper antenna.

While common UHF antennas are cheaper, this does not mean that reception will be ideal in all situations. In general, UHF signals are less efficient than VHF signals. This means that UHF signals are more likely to be affected by bad weather conditions, and sometimes are far more sensitive if the antenna is installed improperly for optimal reception. While this type of antenna was once mono-directional, it is now configured for omnidirectional use. In addition, antennas are designed with current or high definition HD technology which are often equipped with amplifiers that help to enhance and stabilize the device's ability to receive and hold broadcast signals.

Today's outdoor UHF antennas are much smaller compared to popular models before the advent of cable and satellite television. In some cases, outdoor units may not be larger than common table lamps. Indoor UHF antennas may be flat and no larger than a standard sized magazine. The smaller dimensions make it easier to mount the antenna to a location that provides the best reception without requiring a lot of space.
