The equiment are specially designed for the set-up and maintenance of HF, VHF, UHF transmission stations.

They measure in watt:

-         The power supplied by a transmitter

-        The power reflected by the “feeder-antenna” unit from 2 MHz to 2.7 GHz.

Very simple to use and extremely accurate measurement.

Excellent site or laboratory instruments, sturdy and rainproof.

A shoulder bag is available to carry and protect the instruments.

PRINCIPLE

The main component is a wideband bi-directional coupler which simultaneously samples and detects a fraction of the incident power and part of the reflected power.

After amplification, the voltage supplied by the bi-coupler branch detectors is used to indicate the measurements on a galvanometer graduated in watts.
