nas provide efficient operation over the comm band. Antennas should be installed per
manufacturer's recommendations. Additional recommendations are as follows:
2.3.3.A. Mount antenna on a flat metal surface or install a ground plane at least 18
inches square.
2.3.3.B. The antenna should be well removed from any projections and the engine(s)
and propeller(s). Also, for satisfactory operation, the antenna isolation be-
tween a communications transmitter antenna and a nav receiver antenna, as
well as between dual comm antennas, should be a minimum of 30 dB. VHF
antennas mounted on top and bottom have approximately 30 dB isolation. A
horizontally polarized nav antenna and a vertically polarized comm antenna
will have practical values from 10 to 30 dB.
2.3.3.C. If both comm antennas must be top mounted or both bottom mounted, anten-
na isolation between comms may not be adequate to prevent re-radiation. In
single audio panel installations, re-radiation can be prevented by use of the
XMT-REC interlock. Refer to Installation Bulletin #194. In dual audio panel
installations where simultaneous operation of both comms is desired, the
XMT-REC interlock is not recommended.

Cable Harness and Connector Assembly

The KY 96A, KY 97A uses a special connector that mates directly with the printed cir-
cuit board inside the unit. Assembly of the connector is as follows:
2.3.4.A. Contact Terminal Assembly using Molex Crimper (see
2.3.4.A.1 Strip each wire 5/32 inch for contact terminal, P/N 030-01107-00XX. (The last
two digits of the part number indicates the number of terminals required).
2.3.4.A.2 Open the Molex HT 1921 hand crimper with the engraved side toward the op-
erator. Place the conductor tab section of a contact terminal on Anvil A with
the contact portion facing away from the operator. Close the crimper slightly
until the contact tabs touch the female jaw.
2.3.4.A.3 Insert the stripped conductor until the insulation is even with the side of the
crimper facing the operator. Crimp the conductor tabs by squeezing the han-
dles together until the jaws are fully closed or a sufficient crimp is obtained.
2.3.4.A.4 Move the lead to Anvil A. Place the insulating tab section on Anvil A. Crimp
again until the jaws are fully closed or until a sufficient crimp is obtained.
2.3.4.B. Contact Insertion into Molex Connector Housing
After the contact terminals have been installed on the wiring harness, the contact ter-
minals can be inserted into the proper location in the connector housing (P/N 030-
01094-0080). The terminal cannot be inserted upside down. Be sure to push the ter-
minal all the way in until a click can be felt or heard. The self-locking feature can be
tested by gently pulling on the wire.
