	Very high frequency - Wikipedia, the free encyclopedia
		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) and aircraft communications.
		In most countries, the VHF spectrum is used for broadcast audio and television, as well as commercial two-way radios (such as those operated by taxis and police), marine two-way audio communications, and aircraft radios.

		VHF radio is radio transmission in the VHF frequency range, as a means of short-range, line-of-sight verbal communication.
		Marine VHF radio in the frequency range 156 to 174 MHz, is mainly used for collision avoidence, summoning rescue services and communicating with harbours and marinas.
		A marine VHF set is a combined transmitter and receiver of VHF transmissions on standard, international frequency bands known as "channels".

		On all Shakespeare VHF Marine antennas the receiving zone is 360 degrees or omni-directional.
		On all Shakespeare VHF Marine antennas the beam width is between 24 and 26 degrees.
		VHF antennas come in gain categories, like 3-dB, 9-dB, etc., which are a measure of how efficiently the antenna deals with the signal it is fed from the radio.

	Chuck Husick on BoatUScom
		Success in transferring energy from the radio's radio frequency power amplifier to the atmosphere depends on both the type of antenna you chose and the specific coaxial cable used to connect the radio to the antenna.
		At the frequencies used for marine VHF communication (centered on the two meter band, 155 MHz) a considerable amount of the transmitter energy can be lost during its passage through the antenna cable.
		VHF antennas are often described as having a certain amount of "gain", an indication that they can increase the strength of the transmitted signal.

	VHF Radio
		Unlike a cell phone a VHF radio call for assistance can be heard by any vessel within radio range that is monitoring channel 16, increasing the likelihood of receiving a timely response.
		The VHF marine band is comprised of a spectrum of frequencies ranging from 156 – 157.5 Mhz for transmission and 156 – 163 Mhz for reception.
		The device measures the ratio of the current (or voltage) that is moving from the radio toward the antenna to the current (or voltage) that is traveling from the antenna back to the radio.

	DF5AI.NET - Amateur Radio Propagation Studies
		Bob has studied VHF propagation systematically over many decades and, yes indeed, I can imagine that he has found systematical features which may be used for prediction purposes.
		I asked Bob to write a blue print paper allowing VHF radio amateurs to test his prediction method in practice.
		Between the northwest of Spain and the Canary Islands, intense inversion layers are found between 1000m and 2000m altitude indicating discontinuities in air temperature and, in particular, in air humidity.

	VHF Community Radio Electronics - An Introduction
		The VHF signal can either be generated directly, or the oscillator can oscillate on a lower frequency eg a third or half that desired and then followed by a tripler or doubler stage.
		But the effect of radio waves bouncing off buildings etc tends to twist the polarisation of your signal from horizontal to vertical and vice versa, so your signal will still be picked up by the other sort of aerial.
		VHF radio waves do bend a bit so you'll get a bit more coverage than you can see, but its hard to say how much.
