5.B.(5)(f) Short Wire to Vertical Stabilizer Antenna Mounting Location
(refer to
“Figure 2004 - Typical Short Wire to Vertical Stabilizer Antenna” )
The most common form of short grounded wire antennas have the feedthru
insulator mounted on the upper aft part of the fuselage, as far forward of the
vertical stabilizer as is practical. The antenna wire runs from this feedthru to
the tip of the vertical stabilizer. It is important to ground this wire as high as
possible on the vertical stabilizer to maximize the efficiency and to reduce
the nulls in the pattern. This antenna will generally exhibit maximum
radiation off the side of the aircraft.

5.B.(5)(g) Short Wire to Wing or Horizontal Stabilizer Antenna Mounting Location
(refer to
“Figure 2005 - Typical Short Wire to Wing Antenna” and “Figure
2006 - Typical Short Wire to Horizontal Stabilizer Antenna” )
In installations where the short wire to the vertical stabilizer may not be
practical, consideration may be given to a short grounded wire to the wing
or horizontal stabilizer. While such antennas produce only minimum drag,
they will tend to be directional off the side of the aircraft.
These antennas are also prone to being walked into. Maximum separation
between the wire and the aircraft structure is important, as is maximizing the
length of the wire.
