Remove protective cap on FMA J4 (2.92 mm female coax) and FMA J3. Connect K-type disconnect
plug to K-type disconnect receptacle J4 on the FMA and torque to 7 in-lb (0.79 Nm) or as specified
by the cable manufacturer. Connect the WR34 waveguide assembly to the FMA receptacle J3.
(4) Installation of the Waveguide and Coax Interconnect between the FMA and Externally
Mounted KRFU
(a) Loosely attach the waveguide and coax support brackets to the AIM or LAIM. The
flexib
le wave guide and coax cable assembly kit and its routing are aircraft specific.
(b) Remove the protective covers from the FMA J3 RF TX
. Visually examine connector
ends and make sure that there is no debris in the cavities.
(c) Loosely connect the WR34 flexible waveguide to
the FMA J3 waveguide flange with
sealing gasket. Hand tighten the fasteners.
(d) Loosely attach the waveguide and coax support br
ackets to the AIM or LAIM.
(e) Loosely connect the WR34 to WR28 waveguide adap
ter to the KRFU with sealing
gasket. Apply torque to the waveguide adapter flange for all fasteners as recommended.
(f) Loosely connect the waveguide assembly to the KRFU with a sealing gasket. Make sure
the O-ring is se
ated correctly in the KRFU TX waveguide flange when mating the
waveguide as there is no retaining mechanism. If maintenance is conducted which
requires uncoupling the waveguide from the KRFU TX port, inspect the flange for dirt or
debris and O-ring for damage or if it is misshapen. If required, replace the O-ring and
clean the waveguide flange interfaces.
(g) Apply torque to the KRFU waveguide flan
ge for
all fasteners as recommended.
(h) Firmly attach waveguide support brackets to adapter plate.
The minimum allowable bend radius to the center line for
flexible waveguide is 1 inch (25.4 mm) in
H plane (bend along the long axis of the waveguide) and 0.5 inch (12.7 mm) in E plane (bend along
the short axis of the waveguide). The minimum allowable bend radius for the coax cable is 0.25 inch
(6.35 mm). Refer to Figure 4-11.

(5) Connecting the FMA Interface, KRFU Power
, an
d Control Interfaces
The control signals for the KRFU are supplied from the KANDU and are connected to KRFU
J2 receptacle.
