E. Connect Antenna Coupler UC-584S to Aircraft upper Transponder Antenna as follows:
(as applicable)
NOTE: For Transponder–1 Adjustment/Test
(1) Place Antenna Coupler (2) over the antenna (3) , guiding antenna in to the slot on the
bottom of the coupler.
(2)
Lock Antenna Coupler (2) into place by pushing lever on the side of the coupler into a
down and locked position.
NOTE: Coupler must be tightly pressed and locked in place for Test Set to function
correctly. Coupler will lock into place when the black rubber gasket is not
completely depressed against the aircraft, but the Test Set will not measure
functions accurately.
CAUTION: DO NOT CONNECT COAX CABLE TO IFR-6000 ANT PORT. DAMAGE
TO EQUIPMENT WILL OCCUR.
(3) Connect long RF coaxial cable (1) between the Antenna Coupler (2) and Test Set RF
I/O Connector.
CAUTION: THE RF COAXIAL CABLE CAN BE A TRIPPING HAZARD. MAKE
SURE TO SECURE THE CABLE. PERSONAL INJURY AND DAMAGE
TO THE ANTENNAS AND TEST EQUIPMENT COULD OCCUR.
(4) Temporarily secure the coaxial cable to the aircraft with tape. Tape can be removed
after the test is completed.
(5)
Push Antenna Coupler (2) firmly against the aircraft skin until the black rubber gasket
on the rim of the coupler is completely depressed tightly against the aircraft.
F. Connect Antenna Coupler UC-584 to Aircraft lower Transponder Antenna as follows: (as
applicable)
NOTE: For Transponder–2 Adjustment/Test
