A radio operates by sending and receiving radio signals. A radio signal is a form of energy that moves in waves, just like sound waves. MHz (or megahertz) is a unit of measurement used to measure radio waves, UHF (Ultra High Frequency) and VHF (Very High Frequency) represent the frequency types of radio transmit. The frequency and wavelength differences between the UHF and VHF bands lead to the unique capabilities of these two types.
For most radios, the answer to this question is no. Some high-end public safety-grade radios can talk on both bands, but they are not a practical option for most radio users. Before buying a radio, it's important to know the existing frequencies of your radio system, because, for them to communicate with each other, they need to be the same.
Every wireless communication device has an operating frequency , which means that to communicate, regardless of whether it is VHF or UHF, the radio needs to be on the same frequency.
So, UHF or VHF, which is better? They all come with distinct pros and cons, understanding these differences will help you identify the best signal frequency for your needs, each having a specific application in a specific field. Here are some new models of Hytera UHF/VHF Radios.
