A UHF antenna is a radio wave antenna that operates in the frequency range between 300 megahertz and three gigahertz.
UHF stands for ultra-high frequency, which is used when describing how fast an electromagnetic wave can transmit information. The higher the UHF number, the faster it transmits information (and vice versa). As mentioned in our intro about uhfs, they operate at frequencies between 300 MHz to 3 GHz; this means that uhfs are very good at transmitting data quickly! They are often used in TV broadcasting because they make it possible to send multiple channels of programming over the airwaves.
Uhf television transmissions are high-frequency waves with a wavelength between 3 meters and 1 meter. The FCC created the UHF range to allow room for additional channels from those in the VHF spectrum (which ranges from 30-300 MHz). They can transmit digital as well as analog signals. UHF antennas typically have a wider plug than other TV antennas because their signals are transmitted on a wider bandwidth.
