VHF, in full very high frequency , conventionally defined portion of the electromagnetic spectrum including any radiation with a wavelength between 1 and 10 metres and a frequency between 300 and 30 megahertz. VHF signals are widely employed for television and radio transmissions.
Read moreWhat is VHF and UHF?
VHF represents “Very High Frequency” while UHF represents “Ultra High Frequency.” The FCC also determines who can operate in each band and who has priority if more than one user is operating.
Read moreHow do you transmit VHF?
Use an “open channel” to performance the check (channels 68, 69, 71, 72 and 78A). Turn radio to one-watt power setting, and key the microphone. Call “radio check” three times, followed by your boat name and location. Wait for a reply confirming someone has heard your transmission.

Below we will discuss a few of the most common factors found to affect VHF communications: Transmitter Power, Intervening Topographical Features, and what can be considered to be the most important factor affecting VHF range, antenna height .
Read moreWhich wave is used for VHF communication?
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz) , with corresponding wavelengths of ten meters to one meter.
