5009, Directional RF Power Sensor

Dual-Socket, Directional RF Power Sensor

Connect to the 3141, Channel Power Monitor Display via RJ42 Interface

The 5009, RF Power Sensor is a highly economical RF power measurement tool offering reliable results for hundreds, not thousands of dollars. The dual-socket, Thruline® RF power sensor's flexible design allows the user to select from a variety of Bird DPM Series, Plug-In Elements that span over a wide range of frequencies and power levels as well as dozens of field changeable RF connectors to tailor the unit to your needs.

The 5009 RF Sensor provides both forward and reflected power measurements that are NIST traceable. These sensors are intended for use at the transmit combiner output, in order to provide both combiner power, as well as antenna VSWR information.

  • Provides power readings in HF frequency bands
