Additional Items Required
Additional items you will require, but which are not in the SV-XPNDR-261/262 package, include:
Antenna and fixing hardware. The SV-XPNDR-261/262 is compatible with transponder
antennas commonly available.
Cables and TNC Female connector (or TNC Female to BNC Male adapter). You need to
supply and fabricate all required cables (or cable and connector is included with your
transponder antenna). Guidance on cable types is given below.
Mounting hardware: To secure the SV-XPNDR-261/262 tray to the airframe you will need at
least 3 flat head screws and three self-locking nuts. If the aircraft does not have existing
mounting provisions you may need to fabricate additional brackets to support the SV-
XPNDR-261/262 tray.
Electrical Connections
SV-XPNDR-261/262 Harness Construction
For connecting the SV-XPNDR-261/262, Dynon
Avionics offers the optional SV-HARNESS-XPNDR
harness (pictured at right). This harness is not
included with the SV-XPNDR-261/262. It comes with
15 feet of wire, and the connector is pre-wired. If
required, the harness can be shortened, or
lengthened (length is not critical). Table 75 – SV-
HARNESS-XPNDR Pinout (below) reflects the wiring
colors of the SV-HARNESS-XPNDR.
The SV-XPNDR-261/262 has a single D25F connector
which provides the data and power inputs to the SV-XPNDR-261/262. A single TNC female
coaxial connector attaches to the antenna.
Because the SV-XPNDR-261/262 can be mounted in a variety of locations, the harness length
requirements will vary between various aircraft.
