30 - 500 MHz (VHF UHF)

VHF UHF Antenna spectrum

VHF UHF Antennas are very popular for Line of Sight (LOS) communications. Such comms include television, mobile radio (LMR, SMR), walkie-talkies, military satcom, aviation, amateur radio, etc. Within this spectrum, waves propagate mostly in straight lines with a low loss, as the wavelength is short enough that the wavefront is not significantly attenuated by its groundwave component, while at the same time, it is long enough to interact with atmospheric bulk properties and plasma, allowing signals to propagate beyond the horizon, oftentimes well beyond the same.

Within the present spectrum, a number of dual-band antennas are listed, one covering the a VHF frequency and the other, a UHF band, permitting the user to operate two bands within a single aerial. Also, Military Satcom and remote control radios operate at the transition between VHF and UHF.

Perhaps the most popular of all services within this region of the radio spectrum is Television. Traditionally, it ranged from 50 MHz (channel 2) to 216 MHz (channel 13) at VHF, and from 470 MHz (channel 14) to 806 MHz (channel 69) at UHF. With the introduction of spectrally efficient Digital TV, the Television spectrum is being reallocated to other services, with most HDTV channels now residing only within UHF.
