(4) Installation of the Waveguide and Coaxial Cable Interconnect Between the TMA and
KRFU
(a) Loosely attach the waveguide and coax support brackets to an
tenna interface mount or
the tail empennage structure. The flexible wave guide and coax cable assembly kit and
its routing is aircraft specific.
(b) Remove the protective covers from the TMA J3 RF TX. Visually inspect connector ends
and make sure that th
ere is no debris in the cavities.
(c) Loosely connect WR28 flexible waveguide to TMA J3 wavegu
ide flange with sealing
gasket. Hand tight the fasteners.
(d) Loosely attach the waveguide and coax support brackets to the antenna in
terface mount
or the tail empennage structure.
(e) Loosely connect the waveguide to KRFU with a sealing gasket.
(f) Apply torque to KRFU waveguide flange for all fasteners in defined sequences as
recommended.
(g
) Firmly attach the waveguide support brackets to the adapter plate or the tail empennage
structure.
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 2-8.
