DESCRIPTION:
The Bird 4022 is a directional RF power sensor designed for accurate measurement of forward and reflected power across a frequency range of 25 MHz to 1 GHz. It is used to monitor transmitter output, verify antenna matching, and assess RF system performance in VHF and UHF applications.

The sensor enables directional power measurement, allowing identification of reflected power caused by impedance mismatches and helping protect transmitters and associated RF equipment. It is compatible with Bird RF power meters and monitoring systems and is suitable for laboratory, production, and field environments.

The 4022 directional power sensor is commonly used in broadcast, public safety, land mobile radio, and general RF communications systems.
