摘要:
PROBLEM TO BE SOLVED: To provide an antenna feeder circuit for medium wave broadcasting which has a simple configuration, facilitates impedance matching, and has excellent lightning resistance.
SOLUTION: A high frequency transformer having the lightning resistance improved is connected to an impedance matching circuit connected between a broadcaster for medium wave broadcasting and an antenna, and the primary coil of the high frequency transformer is connected to the impedance matching circuit. The secondary coil of the high frequency transformer is connected to the antenna via a series coil for canceling the imaginary term component of antenna impedance, and impedance conversion is efficiently performed by the high frequency transformer, and a ball gap is inserted to an antenna base part against lightning surge exceeding expectations.
