    • PURPOSE:To improve a radio receiving condition in an electric railcar by transmitting radio wave to a transmission antenna provided in parallel to the railroad of the electric railcar, receiving the transmitted wave in the electric railcar during travelling, and transmitting it as a radio wave into the electric railcar. CONSTITUTION:A receiving antenna 3 is provided on the roof part of respective electric railcars 1. The distance between a transmitting antenna 2 and the receiving antenna 3 is placed at such a very closed distance as about 2m from the starting station to the terminal station. The electric railcars 1 during proceeding receive a radio program signal wave from a transmission station at the starting station with a receiver 3a. The received radio wave is sent to an AM system or FM system radio frequency receiver 5 for an in-electric railcar broadcasting placed in a conductor room etc., and the output signal is connected to an in- electric railcar transmitting antenna 6 and broadcasted into the electric railcar. Then, a passenger 7 having a small cheap portable radio 8 receives a strong radio wave from the in-electric railcar transmitting antenna 6 at close range and can hear a good tone quality radio broadcasting with an earphone 9.
