The length and routing of the external cables must be carefully planned before at-
tempting the actual installation. Avoid sharp bends or locating the cable near aircraft
control cables. The cables should be of a length to allow for a “maintenance loop”.
That is, the length should be adequate to access and extend the connectors aft of
the panel for future maintenance purposes. Excess cabling should be secured and
stowed by tie-wrapping until such maintenance is required.

The cables should be supported firmly enough to prevent movement. They should
be carefully protected wherever one may chafe against another or against some oth-
er object. Extra protection should be provided in all locations where the cables may
be subject to abuse. Shields on shielded wires should be grounded as shown on
the system interconnection diagrams.

Shields should be carried through any obstruction via a thru-bulkhead connector. If
shielding cannot be carried through by use of a bulkhead/connector pin, precautions
should be taken to ensure each segment of the shielded lead be grounded at only
one point. A ground connection of not more than two inches in length should be
used. The preceding discussion does not apply to coaxial and quadraxial cable.

Antenna Transmission Line Loss Considerations
NOTE:
The total losses in the coaxial cable run and inter-
connects between the antenna(s) and the KXP 2290
transponder must not be less than 0.5 dB and must
not be more than 2.0 dB at 1030MHz.
