FABRICATION OF THE AN/APR-39(V)1, AN/APR-39(V)2, AN/APR-39A(V)1 AND THE AN/APR-39A(V)4
RADAR SIGNAL DETECTING SET, ANTENNADETECTOR CABLES FOR AH-IF, AH164A/D, CH- 47D/E, OH-58A/C/D, UH-IH/V, AND UH-60A/L/Q/EH-60A HELICOPTERS, TB 1-1500-351-20-1

The purpose of this Technical Bulletin (TB) is to provide the necessary
instructions for local fabrication of the AN/APR-39(V)1, AN/APR-39(V)2, AN/APR-
39A(V)1 and the AN/APR-39A(V)4 Antenna-Detector cables and allows the cables to be
replaced through attrition. It is recommended that if at least one Antenna-Detector
cable requires replacement that all four (4) cable assemblies be replaced at the same
time to prevent any line loss.
