The differences between UHF and VHF frequencies and radios

Your cell phones and two-way radios all work in the electromagnetic wave, but the frequency range is different to stay in the rules of communication. UHF and VHF frequency bands are a part of a two-way radio communication range. So, how to know how to choose and applicate the UHF and VHF radios? And what's the VHF frequency range?

Differences between UHF and VHF

The communication range of UHF radio is shortened than VHF radio. Because UHF has a shorter frequency wavelength, it is subject to more interference during propagation, but it is allowed to occupy a larger bandwidth. In the short wavelength of UHF radio, the size of the radio wave is directly related to the transmission length and the receiving antenna. Typically, UHF antennas are short and wide. VHF is commonly used in FM radio(Like NOAA channels work on 162MHz), radio, long-range data communications, and maritime communications(Marine radio like RM40). VHF is very popular in professional applications, the most famous corporate use being Wal-Mart. Since VHF radio waves are longer and suffer less interference during transmission, the call distance is longer than that of UHF.

The VHF frequency range

VHF works between 30MHz to 300MHz.

Here is the frequency range limitation of the VHF application

  • 50–54 MHz: Amateur Radio 6-meter band.
  • 87.5-108 MHz: FM Radio broadcast band and 92-108MHz is a business broadcast band in the US.
  • 108–118 MHz: Air navigation beacons VOR and Instrument Landing System localizer.
  • 118–137 MHz: Airband for air traffic control, AM, 121.5 MHz is an emergency frequency
  • 144–146 MHz: Amateur Radio 2-meter band (Extends up to 148 MHz in some Regions).
  • 150-156 MHz: "VHF business band," public safety, the license-free MURS radio and other 2-way land mobiles, and FM.
  • 156–174 MHz: VHF maritime mobile band for maritime two-way radio on ships. 156.8 MHz (Channel 16) is the maritime emergency and contact frequency.

Here are 3 examples of MURS VHF frequency radio and Marine radio.

RT47V, the frequency channels of MURS are:

  • 151.8200 MHz
  • 151.8800 MHz
  • 151.9400 MHz
  • 154.5700 MHz
  • 154.6000 MHz

And the high power of it is 2w. And the communication range is about 2 miles.

Here is the guide to our MURS radios and the main specifications. New commercial VHF radio RT81V is also a good example.

The frequency range is 136-174MHz, and there are 32 channels divided into 2 Zones. It is a DMR long-range radio by high power, so it is a licensed radio.

If your business is allowed to work in the VHF commercial range, you can use this radio in law. If not, the RT47V is also a good choice.

RM40 Digital Marine radio



And the max communication range is about 10nmi, and check the parameters on The RM40 and your sailing life. So, if you are interested in Retevis VHF radios, you can describe your application to us, and then, we can recommend the fittest radio to you. Email us at, or share in the comments below.
