(b) Before proceeding with the KRFU installation, connect the WR42 waveguide to 2.92 mm
coaxial connector adapter to KRFU J4 RF RX.
1 The adapter allows connection between a WR-42 waveguide cover flange
UG595/U per MIL-DTL-3922/54 (modified with threaded mounting holes) and a
2.92 mm coaxial connector.
2 The WR42 waveguide side of the adapter has a mechanical flange interface with
four 0.117 inch (2.97 mm) diameter through holes for mating with KRFU J4.
3 The WR42 waveguide to 2.92 mm coaxial connector adapter is shown in Figure 2-6.
Figure 2-6. WR42 Waveguide to 2.92 mm Coaxial Connector Adapter
(c) Remove the protective covers from the KRFU J4 and WR42 waveguide to 2.92 mm
coaxial connector. Visually inspect connector ends and make sure that there is no debris
in the cavities.
(d) Install an O-ring and mount the adapter onto KRFU J4 with four screw
s. Firm tight the
WR42 waveguide to 2.92 mm coaxial connector to KRFU waveguide flange for all
fasteners in opposite sequences. Do not use power tools to torque connection.
(e) Attach the KRFU assembly to the KRFU interface mount with
fasteners and tighten.
Minimum torque recommended to compress the thermal pad is 22 in-lb (2.5 Nm). Apply
torque to the fasteners in defined sequence for firmly mounting to the antenna interface
mount or the tail empennage of the aircraft. Do not use power tools to torque connection.
(f) Install one end of the ground straps to the antenna interface mount or the tail
e
mpennage stru
cture plate at labeled ground points with screw and washers.
(g) Install the other end of the ground straps to grounding po
ints on the KRFU. The KRFU
bonding strap arrangement is shown in Figure 2-7.
