Apr/2006 - Honeywell KHF 1050 System Installation Manual

Commonly used aircraft HF antennas will generally fall into one of four
categories:
• "V" (Referring to the V shape formed by the antenna wire) and Long wire
antenna.
• Short grounded wire antenna.
• Shunt antenna.
Characteristics of these commonly used antennas and the compromise
associated with each type are described below, so the installer can select the
antenna that is best suited to a particular aircraft and type of operation. All
antennas should be installed in a manner that does not jeopardize the safe
operation of the aircraft.
5.B.(5)(a) "V" and Long Wire Antenna Mounting Location
Because of their generally good performance, consideration should be
given to the use of "V" and long wire antennas on all installations, except
very high speed fixed wing aircraft and helicopters. Wire antennas are not
recommended for use on helicopters, due to safety concerns in the event of
an antenna wire breakage.
"V" and long wire antenna performance will be enhanced by striving to meet
the following criteria:
• Maximize the length of wire (up to approximately 60 feet or 18 m.). The
total length of the antenna should be at least 25 feet (7.6 m).
• Maximize the separation between the antenna wire and the aircraft
structure. This is usually achieved by attaching the tensioner as high as
possible on vertical stabilizers.
