Two types of shunt antennas are commonly used. The most
preferable type, on a fixed wing aircraft, is designed
by the airframe manufacturer as a part of the airframe
structure. It is most often an electrically isolated
section of the leading edge of the vertical stabilizer,
grounded at the top. The other type of shunt antenna is
often referred to as a "tranline" or "towel bar", which
is simply a rod or tube run external to a section of
the airframe and grounded.
Shunt antennas are suitable for high altitude aircraft
because they do not develop extremely high voltage but
do not develop extremely high RF current (up to 50
amps).
Location
A shunt antenna that is built into the leading edge of
the vertical stabilizers has become popular on many jet
aircraft. Such an antenna provides no drag, exhibits a
rather omnidirectional radiation pattern and if well
bonded can provide moderate to good efficiencies. Good
bonding of the antenna and the KAC 1052 Antenna Coupler
is essential.
