The ORITEL RW521 directional wattmeter is designed for use during the commissioning and maintenance of telecommunications stations from 1.3 to 2.7 GHz, for rural UHF mobile telephony networks in particular.
It measures the power supplied by a transmitter in dBm and the power reflected by the "feeder-antenna" assembly in order to determine antenna suitability .
