Precision Bird Plug-In RF power sensor covering 144 MHz to 244 MHz with a 25 W to 500 W measurement range, designed for accurate forward and reflected RF power measurements with Bird Thruline wattmeters in land mobile radio, broadcast, amateur radio, and RF test applications.



DESCRIPTION:

The Bird Plug-In RF Power Sensor is a precision interchangeable measurement element designed for use with Bird Thruline RF wattmeters and compatible Bird RF measurement systems. Covering the 144 MHz to 244 MHz frequency range with a power measurement range of 25 W to 500 W, the sensor provides highly accurate forward and reflected RF power measurements for VHF communications systems.

Designed for Bird's renowned Plug-In Element architecture, the sensor allows engineers and technicians to quickly configure a Bird wattmeter for specific frequency and power requirements simply by changing the measurement element. This modular design has made Bird Thruline wattmeters the industry standard for RF power measurement across broadcast, land mobile radio, military communications, amateur radio, and RF laboratory environments.

The sensor is ideal for testing VHF transmitters, repeaters, base stations, RF amplifiers, antenna systems, and communication infrastructure operating within the 144 MHz to 244 MHz frequency band. When installed in a compatible Bird wattmeter, the element provides reliable measurement of both forward and reflected power, enabling verification of transmitter performance and antenna system matching.

Manufactured to Bird's high standards of accuracy and durability, the sensor offers long-term stability and repeatable measurements, making it suitable for field service, preventive maintenance, production testing, and laboratory calibration applications.
