The Model 4042 from Bird Technologies is a directional power sensor that operates from 100 MHz to 1000 MHz. It provides both forward and reflected composite power measurements with ±5 % of full scale accuracy and has a power range up to 500 W and is also NIST traceable. This sensor is intended for use at the transmit combiner output, in order to provide both composite output from the combiner power, as well as antenna VSWR information. It is available in a module that measures 132 x 96.5 x 35.5 mm with N-type male/female connectors.
