Reflectometer units for short-wave senders

摘要

Reflectometer equipment has been developed for use on 100 kW and 250 kW high-frequency (h.f) senders. The equipment provides indications of carrier power, reflection coefficient, unbalanced-to-balanced power ratio, and peak values of maximum line voltages. Trip setting and logic circuits are provided to give increased protection to the senders during normal operation. Eight units have been provided for the Far Eastern Relay Station at Tebrau.
