ARTIFICIAL AERIALS FOR TRANSMITTER TESTING
A dummy load is an artificial aerial that is used for making measurements and performing tests on radio transmitters without actually radiating a signal into the air. Radio operators should routinely use dummy loads to tune up on crowded channels, and only when the tuning is completed transfer power to the live antenna. In some countries, this procedure is not merely good manners, but required by law (even if often ignored).
