Is The Walkie-talkie On Board VHF Or UHF?

The Marine Radio used on board, both VHF and UHF can be used. The VHF band is a maritime channel walkie-talkie with built-in international, US and Canadian channels. Generally, FM is not required, and the UHF band walkie-talkie needs to be frequency-modulated.

According to the electromagnetic theory of the British physicist Maxwell, the higher the frequency, the shorter the wavelength, the stronger the ability of the wave to penetrate the building, but the weaker the diffraction ability; the lower the frequency, the longer the wavelength, the electric wave penetrates the building. The weaker the ability, the stronger the ability to diffract.

Therefore, a walkie-talkie used in an open environment such as the wilderness or the sea requires radio waves with high diffraction power, so it is appropriate to use a VHF walkie-talkie (156 - 163.275 MHz); in an environment with high density and many obstacles, for example Communication between the cabin and the deck requires radio waves with strong penetrating power, so UHF walkie-talkies (400-470MHZ) should be suitable.

In summary, the two-band intercom on the ship can be used, you can choose the intercom in different frequency bands according to the needs of your ship. For more information about the marine walkie-talkie, you can consult the VHF Marine Radio Manufacturer
