DESCRIPTION:
The Bird 4025 is a directional RF power sensor designed for accurate measurement of forward and reflected power over a frequency range of 100 kHz to 2.5 MHz. It is used to monitor transmitter output, verify antenna matching, and assess system performance in low- and medium-frequency RF applications.
The sensor enables directional power measurement, allowing identification of reflected power caused by impedance mismatches and supporting protection of 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 4025 directional power sensor is commonly used in LF and MF broadcast, navigation, maritime, and general RF communications systems where reliable low-frequency power measurement is required.
