5.C. Interwiring and Cable Fabrication
5.C.(1) Fabrication and Routing
Figure 2033 provides a KHF 1050 HF Communication System
interconnect summary.
Cabling must be fabricated according to the interwiring
diagrams. The length of the wires to parallel pins should
be approximately the same length, for best current
distribution.
Wires for optional functions are shown on the interwiring
diagrams. The actual use of these wires will depend upon
the installation, customer requirements and capability of
the units installed.

KHF 1050 SYSTEM INSTALLATION MANUAL
• The antenna diameter should be a minimum of 1 inch
(2.54 cm) and constructed out of a highly conductive
material. Copper or aluminum is generally used, with
silver plating being recommended. Stainless steel
should be avoided due to its high resistance. This
antenna should be a continuous piece (non-spliced)
and should be well bonded at both ends.
• A minimum antenna length of 12 feet (3.7 m) should
be used. The feedline coax length should be limited
to 6 inches (15 cm).
• It is preferable to attach the antenna to a
protruding surface, such as a tail boom or a
stabilizer element. Attaching to a wide section of
the fuselage will generally give poor performance.
