SA-006 Communication
Antenna for use in Composite Aircraft
The SA-006a COM antenna is designed for reception of vertically
polarized energy in the frequency range of 118 to 136 MHz. The antenna
is constructed of Alclad 2024-T4 aluminum stampings .016” thick riveted
together to form a vertical dipole with appropriate pieces for impedance
matching. The voltage standing wave ratio (VSWR) is less than 2:1 over
the frequency range of 118 to 136MHz. There may be variations in VSWR
due to installation variations. This antenna requires a rectangle of
space 26” vertically and about 10” horizontally. The antennas were
designed to be mounted on the inside surface of fiber glass fuselages or
vertical tails. This antenna was designed and tuned to be mounted as
described in these instructions and it is unknown what the VSWR might be
in other locations though if installed as described it should work just
as well.The antenna must be
mounted vertically as shown in the installation drawing and installation
manual.
This antenna
is ideal for use in the vertical fin of a fiberglass sailplane or in the
fuselage of a wood or steel tube and fabric glider. Note that they
are designed to be oriented vertically (standing up) - not horizontally
(laying down). Modern carbon fiber sailplanes are designed to
accommodate antennas in the vertical fin. The fin is specifically
built using fiberglass rather than carbon fiber for that reason.
These antennas will not work in metal aircraft.
Connector
Type: 2 crimp or solder connectors
