Antenna Applications VHF and UHF Antennas UHF/VHF/FM Receiving Antenna Another application for antennas that I’m sure we’re all familiar with is VHF and UHF antennas, which stand for Very High Frequency and Ultra High Frequency. You’ve all seen the tall transmitting towers. They need to be large enough to achieve the desired frequency and provide a large range of coverage. VHF and UHF covers frequencies from 3 MHz to 3000 MHz and includes television and FM radio broadcasting. The most common type of receiving antenna is called a Yagi array antenna. The array has different size conductors to receive different frequencies. Yagi arrays are highly directional, so they should always be pointed towards the transmitter tower.

Notes The length of the radiating element determines many of the properties of the dipole antenna
