VHF radios are suited for long distances in and outdoor use. UHF radios operate at a higher frequency . This makes them ideal for wireless communications that need to penetrate through buildings, walls, or concrete. UHF radios are suited for indoor communication solutions, where obstacles are easily penetrable.
Read moreWhich is better UHF or VHF radio?
UHF is the better all around signal and is by far the most popular, so if you are in doubt, choose UHF. UHF signals don’t travel quite as far outdoors as VHF signals, but they do a better job of penetrating wood, steel, and concrete, giving you better range and performance in urban environments and around buildings.10 Eyl 2008
Read moreWhat range would you expect on a VHF radio?
The effective range of a VHF radio is up to 20 nautical miles and often much further, depending on the elevation of land-based receiving stations. A VHF radio with Digital Selective Calling (DSC) and GPS functions will provide you with even greater safety and convenience.
Read moreHow long is a VHF wave?
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 determines the range of a VHF radio?
Essentially, the Range is determined by the position & length of the Antenna and how many Watts of power the device is able to put out . A hand held VHF only puts out 5watts of power, while a fixed mount device puts out 25watts.
Read moreHow far can a UHF radio transmit?
Since UHF transmission is limited by the visual horizon to 30–40 miles (48–64 km) and usually to shorter distances by local terrain, it allows the same frequency channels to be reused by other users in neighboring geographic areas (frequency reuse).
Read moreHow does VHF propagation?
The primary mode of propagation for VHF radio waves is through direct waves . These travel in a straight line, becoming weaker as distance increases. Transmitting and receiving antennas must be able to ‘see’ each other for communications to be effective, so antenna height is critical in determining range.
