VHF

n. range of radio frequencies between 30 and 300 megahertz

Very high frequency (VHF) is the radio frequency range from 30 MHz to 300 MHz. It is also known as the meter band or meter wave as the wavelengths range from ten to one meters. Frequencies immediately below VHF are denoted HF, and the next higher frequencies are known as Ultra high frequency (UHF).Common uses for VHF are FM radio broadcast at 88–108 MHz and  television broadcast (together with UHF). VHF is also commonly used for terrestrial navigation systems (VOR in particular), marine communications, and aircraft communications.VHF frequencies' propagation characteristics are ideal for short-distance terrestrial communication, with a range generally somewhat farther than line-of-sight from the transmitter (see formula below). Unlike high frequencies (HF), the ionosphere does not usually reflect VHF radio and thus transmissions are restricted to the local area (and don't interfere with transmissions thousands of kilometres away). VHF is also less affected by atmospheric noise and interference from electrical equipment than low frequencies. Whilst it is more easily blocked by land features than HF and lower frequencies, it is less bothered by buildings and other less substantial objects than higher frequencies.
