The primary users are properly licensed radio and television broadcasters as well as commercial communication services such as cell phones and two-way radios. Very high frequency is commonly used for FM radio broadcast, two-way land mobile radio systems, long-range data communication, and marine communications, just to name a few.
VHF waves must not exceed the local radio horizon of miles. VHF frequencies are less likely to be interrupted by atmospheric noise, issues with electrical equipment, and other interferences. There are different bands within VHF frequency, including low-band and high-band. Low-band VHF range of 49 MHz includes transmission of wireless microphones, cordless phones, radio controlled toys and more. Despite the potential background noise this a popular option because of the low cost equipment.
Transmission power is limited to under 50 mW, unless you are operating an assistive listening system in the MHz range. Also, a large antenna booster is necessary, measuring as much as 3 feet in length, thus limiting portability. High-band VHF range is popular for professional applications. VHF radios are better suited for outdoor use where line of sight or open terrain is involved. If you need communication at a festival or construction site, these are the right radios for you.
VHF radios are used exclusively in maritime and aviation communications. Subscribe Register For Barrett news and updates Register. This website uses cookies to improve your experience.

The longer wavelength of VHF enable it to travel further than UHF, so VHF radios could be right for you if you are primarily looking for two way radios for outdoor use. VHF radios are used exclusively in aviation and marine communication, and are great for grounds maintenance workers, use in open fields, golf courses, and for outdoor security environments.
Unfortunately it's not possible to convert VHF to UHF etc, as each type of radio contains hardware that enable it to operate on a specific frequency range. If you're buying or hiring more radios to work alongside ones you already use, they need to be of the same type. Will we will be hiring again for our next event.
