The difference between UHF band and VHF band

- Jul 22, 2017 -

On the VHF walkie-talkie and UHF walkie-talkie difference,
According to the British physicist Maxwell's electromagnetic theory, the higher the frequency, the shorter the wavelength, the stronger the ability of the radio to penetrate the building, but the weaker the diffraction capability; the lower the frequency, the longer the wavelength, the waves penetrate the building The ability to be weaker, but the stronger the ability to diffuse. Therefore, in the wilderness or the sea of this open environment used in the walkie-talkie, the need for strong ability to diffuse radio waves, so the choice of V segment (156 - 163.275MHz) that VHF band walkie-talkie more appropriate; and in high density, obstacles Multi-environment, the need for strong wave of radio waves, it should be selected U (400-470MHZ) UHF band that is more suitable for walkie-talkie.
