The TOA YW-4500 is an indoor UHF dipole antenna for TOA wireless microphone systems, mounted on a wall or ceiling. A built-in RF booster makes up for losses on long coaxial runs back to the receiver, and it is powered from the receiver or tuner over the 75 ohm coax. It is used where receivers sit in a rack room away from the stage, such as halls, churches, conference rooms and school theatres.
