Abstract

The invention discloses a transmission method for power supply signals and radiogram radio-frequency signals as well as an antenna amplifier, belonging to the field of automobile antennas. The transmission method comprises the following steps: the antenna amplifier receives the power supply signals transmitted through a coaxial cable from an output end of the radiogram radio-frequency signals, and outputs the radiogram radio-frequency signals through the coaxial cable from the output end of the radiogram radio-frequency signals. The antenna amplifier comprises the output end of the radiogram radio-frequency signals and the coaxial cable. According to the transmission method for the power supply signals and the radiogram radio-frequency signals as well as the antenna amplifier, disclosed by the invention, the power supply signals and the radiogram radio-frequency signals are transmitted through the coaxial cable, thus a power line of the antenna amplifier of an automobile can be saved, and the purpose of saving arrangement of wires is realized; in addition, the radiogram radio-frequency signals transmitted through the coaxial cable are filtered, thus the interference on the radiogram radio-frequency signals further can be prevented, and the quality of the radiogram radio-frequency signals is ensured.
