Figure - Honeywell KTR 2280A Installation Manual

(2) The unit must be kept a minimum of three feet from the antenna. Additionally, the an-
tenna coax cable must not be bundled with the other wiring harnesses to the unit.
(3) The length and routing of the external cables must be carefully planned before attempt-
ing the actual installation. Avoid sharp bends or locating the cable near aircraft control
cables. The cables must be of a length to allow for a "maintenance loop". That is, the
length must be adequate to access and extend the connectors aft of the panel for future
maintenance purposes. Excess cabling must be secured and stowed by tie-wrapping
until such maintenance is required.
(4) The cables must be supported firmly enough to prevent movement. They must be care-
fully protected wherever one can chafe against another or against some other object.
Extra protection must be provided in all locations where the cables can be subject to
chafe. Shields on shielded wires must be grounded in accordance with the system in-
terconnection information.
(5) Shields must be carried through any obstruction through a thru-bulkhead connector. If
shielding cannot be carried through by use of a bulkhead/connector pin, precautions
must 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 must be used. The
preceding discussion does not apply to coaxial and quadraxial cable.
(6) Avoid routing cables near high noise and high power sources.
Quadraxial Cable Preparation
(1) Remove the outer installation 0.900 inch (22.88 mm) from the end of cable, to expose
the outer layer as shown in Figure 2-1.

(2) Push the braid back as far as possible as shown in Figure 2-2. This will be pulled back
up later and soldered to the connector body.

(3) Measure back 0.700 inch (17.78 mm) and remove the outer insulation from the middle
shield as shown in Figure 2-3.
