Abstract : The US Army Aviation Test Board service tested the AS-1922/ARC Homing Antenna to determine its suitability for Army use. The AS-1922 was operated with AN/ARC-54 and AN/ARC-131 Radio Sets on U-6A, U-21A, UH-1H, and CH-47B Aircraft. Operational testing totaling 130 hours was conducted during day and night in simulated tactical situations. False on-course indications were received under various conditions on the U-6A and U-21A. The installation on the UH-1( ) and CH-47( ) helicopters was suitable. The reception range of the AN/ARC-131 Radio Set was reduced substantially with the AS-1922. Three deficiencies and one shortcoming were found during the test. It was concluded that the AS-1922 is not suitable for Army use on the U-6A Aircraft, or for use with the AN/ARC-131 Radio Set; and that the antenna is suitable for use on UH-1( ) and CH-47( ) helicopters, on the U-21A Aircraft as selected frequencies, and with the AN/ARC-54 radio set. It was recommended that the AS-1922 not be accepted for use on Army aircraft until the false on-course indications and the incompatibility with the AN/ARC-131 have been resolved.
