UHF vs VHF: How To Decide What Is Right For you
For individuals who do not have a lot of experience working with two-way radios, it can be pretty easy to confuse frequency requirements during the purchase phase. One of the key questions to address when navigating two-way radio options is: Do I need a UHF or VHF two-way radio?
Sometimes sellers or buyers may assume it is far too basic of a question to be asked, which can lead to costly mistakes! First and foremost it should be noted that UHF and VHF radios can’t communicate directly with each other, so if you’re looking to expand your radio stock you should look to remain within the same band.
Here’s a little more information…
UHF Radios
UHF stands for Ultra High Frequency. These radios operate on frequencies that range from 400-512 megahertz (MHz). Under most usage circumstances, UHF are the better, more broad option. This is a direct result of the frequency waves being shorter, enabling them to penetrate or circumvent common sources of interference including buildings, heavily wooded areas, topographically challenging area, and most urban outdoor settings.
Essentially, UHF two way radios with a good antenna can reach through buildings and around steel, concrete, wood, and earth. For indoor, indoor/outdoor, and urban or suburban settings UHF is the better choice.
VHF Radios
VHF stands for Very High Frequency. These radios operate on frequencies that range from 130-174 MHz.VHF radios are stronger because they have longer frequency waves and remain lower to the ground, enabling them to travel greater distances with less power. Unlike the UHF frequencies, VHF is not able to penetrate common sources of interference as easily, so a clear line-of-sight (or as few obstructions as possible) is preferred.
VHF radios perform well in open fields, golf courses, landscaping, or any other outdoor situation with few obstacles. The antennas associated with VHF radios tend to be longer in order to facilitate reception in the VHF frequency range.
Of course, there are a variety of choices available with either option, as well as an extensive suite of accessories that can help maximize the effectiveness of your two-way radio. Having the correct two-way communications equipment for your environment is critical to ensuring a clear and reliable line of communication.
