The standing wave ratio is a value indicating whether the antenna and the radio wave transmitting station match. If it is equal to 1, it means that the radio wave transmitted to the antenna does not have any reflection, and all are emitted, which is the most ideal situation. If the value is greater than 1, it means that a part of the electric wave is emitted back and eventually becomes heat, causing the feeder to heat up.

Antenna power resistance indicates the maximum power that the antenna can withstand, and is related to the antenna material and physical size, such as the coil diameter of the resonant coil and the thickness of the vibrator. When selecting an antenna, please ensure that the radio transmission power does not exceed the antenna's power consumption, so as to avoid antenna damage. The use of the hand platform in the car needs to be used with an external car antenna. There is no such thing as the power of the hand platform is small and the car antenna cannot be driven.
