Preliminary - Subject to Change Without Notice
NOTE: All nonconductive finishes such as paint, anodizing
Ground strap connections must be totally free of any
non-conductive finishes.
Corrosion resistance for aluminum mating surfaces should
be achieved by cleaning the aluminum surfaces with
Alumiprep #33 (P/N 016-01127-0000), and then applying
Alodine #1001 (P/N 016-01128-0000). Alodine #1001 (as well
as Alodine #600) provides good electrical conductivity,
other Alodine coatings should be avoided.
Only after the shelves are assembled and mounted, and
ground straps installed, may nonconductive or poorly
conductive protective finishes, such as zinc chromate be
applied. Periodic inspection should be made of all bonds
to ensure that corrosion is not occurring. Any observed
corrosion should be cleaned off.
6.B. KAC 1052 Antenna Coupler Installation
6.B.(1)Select a mounting location for the KAC 1052 Antenna Coupler,
referring to Section 5.B.(1).
6.B.(2)Power Requirements
The KAC 1052 Antenna Coupler will operate from a 28 Vdc
power supply. The unit must be connected to the aircraft
power supply with a circuit breaker with not less than 25
Amp rating.
6.B.(3) Grounding Requirements
NOTE: The importance of properly bonding the KAC 1052
NOTE: Except for the ground provided by the feedline coax

films, or zinc chromate, must be totally removed
from the entire mating surface before assembly.
Techniques such as spot-facing or cleaning only
small area of the mating surfaces do not provide
adequate RF bonding.
Antenna coupler to the airframe can not be over
emphasized.
shield, bonding should not be done with braided wire
but with solid conductive straps, typically one
inch wide.
