16.6 TRANSPONDER
16.6.1 DESCRIPTION
A transponder is optional equipment for Jabiru Aircraft. This system consists of the transponder itself
mounted to the instrument panel fascia, the encoder mounted to the firewall and the antenna fitted
under the front of the aircraft.
16.6.2 REMOVAL & INSTALLATION
Note that transponder calibration must be carried out by a CASA-authorised technician. All
transponder maintenance must be carried out by qualified technicians.
To remove transponder, move the mounting screws holding it to the panel fascia. Disconnect it from
the wiring loom and draw it out under the panel. In some applications it may be necessary to remove
the instrument panel fascia for access.
To remove the encoder, undo the thumb-screw and remove it from its bracket. Disconnect the static
tube and electrical loom.
To remove the antenna: disconnect the BNC connector, loosen the lock nut and withdraw the
assembly.
For details of electrical connection refer to the transponder manufacturer’s data.
