Abstract : The patent describes a method and apparatus for adjusting the physical dimensions of an antenna radiating element to its electrically resonant length at a predetermined frequency by coupling a radiation sensitive device between a radio frequency energy source and a dummy load. A direct current meter is coupled to the radiation device to obtain a reading on the meter which is proportional to the radio frequency energy traveling to the load. The value read on the meter is noted and the source of radio frequency energy is switched to the antenna element which is to be tuned. The physical length of the antenna element is shortened or lengthened to bring the reading of the meter to the value obtained when the radio frequency energy was connected to the dummy load. At this point the antenna element has been tuned and its radiation resistance will equal that of the dummy load.
