Version 16.10 AF-6600 AF-5000 Series Install Manual 119
Power/Ground Input
The AF-ADSB can be powered by 10-30 Volts DC. 22 AWG wire is sufficient for wire runs up to 50’ for
this application. Use an appropriate size fuse or circuit breaker for power supply protection to the AF-
ADSB. If 22 AWG wire is used, a 1 or 3 amp fuse/circuit breaker is acceptable. The AF-ADSB must be
connected to aircraft power, and not to any of the AF-5000 power outputs.
Serial RX/TX
All communication between the AF-ADSB module and the AF-5000 is accomplished via a single
bidirectional serial connection. To accomplish this:
• Choose an unused serial port on a EFIS display to connect the AF-ADSB. Note that both the TX
and RX sides of the serial port are needed, and both the RX and TX lines must be connected.
• Connect the AF-ADSB TX wire (pin 3) to the AF-5000 serial RX of your choosing.
• Connect the AF-ADSB RX wire (pin 2) to the AF-5000 serial TX of your choosing.
Antenna Selection and Installation
The AF-ADSB requires its own antenna; it cannot share the transponder’s antenna. The selected
antenna should be installed according to the manufacturer’s instructions. A UAT-specific antenna or a
transponder antenna may be used with the AF-ADSB. Antennas available include (but are not limited
to):
UAT Antennas
AFS P/N: 73,125 Ball and Stick UAT Antenna
Delta Pop (non-TSO):

Transponder Antennas: Any antenna suitable for use with an aircraft transponder will work
with the AF-ADSB.
The following considerations should be taken into account when siting the antenna:
• The antenna should be well removed from any projections, the engine(s) and propeller(s). It
should also be well removed from landing gear doors, access doors or others openings which
will break the ground plane for the antenna.
• The antenna should be mounted on the bottom surface of the aircraft and in a vertical position
when the aircraft is in level flight.
• Where practical, plan the antenna location to keep the cable lengths as short as possible and
avoid sharp bends in the cable to minimize the VSWR (voltage standing wave ratio).
• The AF-ADSB antenna should not be installed within 2 feet (24 inches) of the transponder
antenna.
