UHF stands for “Ultra High Frequency” while VHF stands for “Very High Frequency.” UHF can range from low band (378-512 MHz) to high band (764-870 MHz) while VHF ranges from low band (49-108 MHz) to high band (169-216 MHz). MHz stands for Megahertz and measures the speed of electronic devices.
Which is better VHF or UHF radio?
Radios with lower frequencies (VHF) have longer wavelengths, making them ideal for work across wide areas free from obstruction, as well as outdoor use. UHF radios operate at a higher frequency, which is ideally suited for wireless communications that need to penetrate buildings, walls, concrete, or other barriers.
Is FM radio a VHF or UHF?
Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band is also used.
Which has longer range VHF or UHF?
VHF and UHF Radios Compared – Which Is Best? VHF (136 – 174MHz) signals generally work best outdoors, giving a somewhat longer range for the same power output than UHF (400 – 470MHz). However, VHF signals really do not work well when there are obstructions like buildings around.

Can I use a VHF radio without a license?
Anyone who uses a Marine VHF Radio needs a licence. If you are a sailor, powerboater, kayaker, angler or even a paddleboarder, you will most certainly need a marine radio.
Can UHF penetrate walls?
UHF radio waves generally only go as far as line of sight. Anything in the way of your sight will also interfere with frequency range, such as buildings, tall trees or any other obstruction. The transmission is high enough to penetrate through building walls, making indoor reception a possibility.
How far can UHF 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).
Is UHF or VHF better for outdoors?
The quick answer is: choose VHF if you plan to only use the radios outdoors and in an area that is relatively free of obstructions, such as buildings. If you plan on using the radio indoors, both indoors and out, or outdoors but around buildings, choose UHF.
How far can a VHF radio transmit?
A typical VHF station operates at about 100,000 watts and has a coverage radius range of about 60 miles.
