ABSTRACT:
A test apparatus is disclosed which is particularly adapted for testing survival-type radio transmitters in the field. The apparatus includes an enclosed metallic test chamber into which the antenna of the radio transmitter is placed. A movable load carriage within the chamber applies a load to a predetermined point on the antenna which results in simulating in the test chamber the radio frequency absorption/reflection characteristics of the antenna in free space. A direct measurement of the radio frequency energy absorbed by the load is thus indicative of the performance of the radio transmitter and its antenna in free space.
