What are the regulations for installing a vehicle-mounted radio?
2 Answers
Installation of a vehicle-mounted radio requires that the rated voltage of the radio is basically the same as the generator voltage of the vehicle. Below is relevant information about vehicle-mounted radios: Function: Mainly used for transportation, production scheduling, security command, and other operations. Power and communication range: The power is not less than 10W, typically 25W. The maximum power is 56W for VHF and 50W for UHF. The power supply for the vehicle-mounted radio is 13.8V, with a communication range of over 20 kilometers. In wireless communication networks, the communication range can be significantly increased through relay stations, reaching up to several tens of kilometers.
There are quite a few rules for installing a car-mounted radio. Speaking from over a decade of driving experience, generally, you need a radio operation license to install one—it's not something you can just buy and stuff into your car. Each country has strict regulations on frequencies and usage ranges. For example, in the U.S., you need an FCC license, while in China, it's a permit from the Radio Administration Bureau. The installation location must be safe, and the antenna shouldn't obstruct the windshield view to avoid affecting driving. The equipment must be certified; otherwise, you might face fines. Additionally, while car-mounted radios are useful in emergencies, avoid using them in prohibited areas, like near airports. In short, compliance is key—don’t let small mistakes land you in trouble.
