on the underside of the aircraft), the connector bases
should be sealed with Self-Leveling Green Sealant
(Volume IV or V, Chapter 2) in accordance with the
following procedure.
(1) To keep antenna level, use a locally
fabricated holding fixture. This can be made from the
bottom of a cardboard box.
(2) Insert the antenna through the hole in the
holding fixture.
(3) Ambient temperature shall be a minimum
of 50F prior to priming, mixing and applying
Self-Leveling Green Sealant (Volume IV or V,
antenna connector(s) until level with the conductive
gasket, and allow the sealant to cure for 30 minutes.
Figure 6-4 shows application of the self-leveling green
sealant.
d. Clean and prepare aircraft antenna connectors
e. Mate connectors/cables in accordance with the
applicable aircraft TO/MIM/TM and apply corrosion
protective materials. For antenna connectors/cables,
the preferred method of protection against corrosion is
to seal mated connectors using Stretch Seal Connector
connector tape cannot be used if the aircraft cutout
hole is not at least 1/4 inch greater in diameter than the
connector diameter. A tight wrap is necessary to ensure
a proper seal. To apply stretch seal to antenna
connectors/cables, begin at the base of the antenna
connector and, removing release film as necessary,
wrap the wet side of the tape around the mated
connector with a 50% overlap while stretching the
release tape 25% to 50% ensuring a tight wrap.
Coverage shall be from the base of the antenna
connector to at least 1/2 inch beyond the connector and
onto the insulation jacket of the coaxial cable. Apply
cable spot tie or string tie immediately above and
below the mated connector to secure the free ends of
the tape to ensure it does not unravel. Figure 6-5
shows the finished application of the stretch seal
protective wrap. If connector wraps are not available
or inappropriate, apply a film of Water Displacing
Corrosion Preventive Compound, MIL-C-81309 Type
III (Volume IV or V, Chapter 2) (Air Force can use
MIL-L-87177 Grade B as an alternate) to the shell or
exterior of the mated connector.
