One of the biggest newbies is whether they should buy UHF or VHF radios.
UHF and VHF refer to the frequencies these radios transmit. Which radio type is right for you depends on your individual circumstances and UHF and VHF radios provide differing advantages.
VHF Radio Advantages
VHF radios broadcast at between 30 MHz and 300 MHz. It has a strong diffraction ability and good penetrating power, so the communication distance is not very far in places with many obstructions, but in open places, the communication distance can be very far. Therefore, VHF radios are better suited for outdoor use where line of sight or open terrain is involved. VHF radios are used exclusively in maritime and aviation communications. If you need communication at a festival or construction site, these are the right radios for you.
UHF Radio Advantages
In general, UHF radios are better for indoor use because their wavelengths are shorter and better able to penetrate through steel and concrete. UHF radios broadcast at between 300 MHz and 3 GHz. VHF radio signals tend to degrade more than UHF signals indoors. UHF radios also have shorter antennas than VHF radios, making them a better fit for discreet radio devices or in situations where longer antennas are impractical, such as crowded hallways in schools.
When choosing a UHF or VHF radio, think carefully about your specific needs and pick the solution that best suits your situation. Also, be sure to purchase well-regarded brands, as cut-rate brands will often not perform as well.
