ABSTRACT:
A drive-in movie theater audio system provides sound to the patrons over their car radios and connects to each radio through a novel lead-in which couples the car radio antenna to a transmission bus connected to a central broadcast band transmitter. The lead-in employs a pair of elongated wire sections supported parallel to one another to capacitively couple the broadcast band signal to the car antenna.
