E. Wiring Installation

(1) Route the remote switch harness wire bundle and breakout wiring through the airframe.

(2) Route the antenna coax cable through the airframe.

NOTE

: A longer coax cable, up to 20 feet (6.1 m), may be fabricated if the cable provided is

too short. Use RG-142 or RG-400 coax cable.

(3) Support the wiring and coax cable by clamping or other suitable means, such that the wiring is

properly supported and protected from chaffing and strain. Refer to the aircraft

manufacturer’s written instructions or as described in AC 43.13-1, Chapter 11, § 9 through 12,

as applicable.
