8 Equipment Installation
This section describes the installation of Ping1090 and related accessories
in the aircraft, including mounting, wiring, and connections.
8.1 Unpacking and Inspecting
Carefully unpack the device and make a visual inspection of the unit for
evidence of any damage incurred during shipment. If the unit is damaged,
notify the shipping company to file a claim for the damage. To justify your
claim, save the original shipping container and all packing materials.
8.2 Mounting
The Ping1090 is designed to be mounted in any convenient location in the
cockpit, the cabin, or an avionics bay.
The following installation procedure should be followed, remembering to
allow adequate space for installation of cables and connectors.
•Select a position in the aircraft that is not too close to any high
external heat source. The Ping1090 is not a significant heat source
itself and does not need to be kept away from other devices for this
reason.
•Avoid sharp bends and placing the cables too near to the aircraft
control cables.

ECCN 7A994 Page 13 | 24
8.3 Connections
Whenever power is supplied to the transponder, a 50ohm load
must be provided to the SMA connection. You can use the
supplied antenna or a commercially available 50ohm load.

8.5 Cooling Requirements
Ping1090 is designed to meet all applicable TSO requirements without
forced-air cooling.
Attention should, however, be given to the incorporation of cooling
provisions to limit the maximum operating temperature if Ping1090 is
installed in close proximity to other Avionics. The reliability of equipment
operating in close proximity in an avionics bay can be degraded if adequate
cooling is not provided.
8.6 Wiring Considerations
The Ping1090 was designed and tested using unshielded, untwisted wiring.
There may, however, be technical benefits of improved electromagnetic
emissions and susceptibility to and from the transponder system. Use of
twisted wire can reduce interference and break-through on adjacent audio
wiring if it is not possible to route them separately.
The distance between the Ping1090 and the power adapter is limited by the
impedance of the wire between them. The Ping1090 is powered directly
from aircraft power, and, therefore, the acceptable voltage drop in the
power line is what limits the distance.
The Ping1090 needs an impedance of less than 0.5ohm in the power line
for satisfactory operation. The following table gives guidance for typical
aircraft hook-up wire. Note that different brands may vary –check your
supplier for details.

An alternative to a harness built from individual wires, particularly for a long
cable run, is to use a multi-core cable. Aviation grade cables with 6 or more
cores are often more expensive than individual wires, and, therefore, are
not generally a good choice. For aircraft where those situations do not

UAV-1000711-001
ECCN 7A994 Page 16 | 24
apply, an attractive alternative solution may be to use 3 or 4 pair data
cable.
Please note that not all data cable is suitable for this application. Cables
with solid cores should not be used. Cables should be selected based on
the wear characteristics of their insulation material, including temperature
rating, resistance to solvents and oils, and flammability. Most inexpensive
commercial data cables have poor flammability properties.
8.7 Antenna Installation
8.7.1 Supplied Dipole Antenna
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 other openings which will break
the ground plane for the antenna.
•The antenna should be mounted in a vertical position when the
aircraft is in level flight.
•Avoid mounting the antenna within 1 meter of the ADF sense antenna
or any COMM antenna and 2 meters from the transponder to the
DME antenna.
•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.
Electrical connection to the antenna should be protected to avoid loss of
efficiency due to exposure to liquids and moisture. All Antenna feeders
shall be installed in such a way that a minimum of RF energy is radiated
inside the aircraft.
8.7.2 Conventional OEM Monopole Antenna
The antenna should be installed according to the manufacturer’s
instructions.

UAV-1000711-001
ECCN 7A994 Page 17 | 24
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 other 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.
•Avoid mounting the antenna within 1 meter of the ADF sense antenna
or any COMM antenna and 2 meters from the transponder to the
DME antenna.
•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.
Electrical connection to the antenna should be protected to avoid loss of
efficiency due to exposure to liquids and moisture. All antenna feeders shall
be installed in such a way that a minimum of RF energy is radiated inside
the aircraft.
When a conventional aircraft monopole antenna is used it relies on a
ground plane for correct behavior. For ideal performance, the ground plane
should be large relative to the wavelength of the transmission, which is
275mm. In a metal, skinned aircraft this is usually easily accomplish, but is
more difficult in a composite or fabric skinned aircraft. In these cases, a
metallic ground plane should be fabricated and fitted under the antenna.
The ground plane should be as large as you can sensibly make it. Because
it is a function of the wavelength of the transmission, the smallest practical
ground plane for a transponder is a approx. 120mm per side; as the size
increases, the performance improves, until the ground plane is approx.
700mm on each side. Anything much larger than that size is unlikely to
result in significant further improvement.
The thickness of the material used to construct the ground plane is not
critical, providing it is sufficiently conductive. A variety of proprietary mesh
and grid solutions are available. Heavyweight cooking foil meets the
technical requirement, but obviously needs to be properly supported.

ECCN 7A994 Page 18 | 24
8.7.3 Antenna Cable
The Ping1090 is designed to meet Class 1 requirements with an allowance
of 2dB for loss in connectors and cable used to connect it to the antenna.
Excessive loss will degrade both transmitter output power and receiver
sensitivity.
Allowing for 0.25dB loss for the connector at each end of the antenna cable
assembly leaves an allowance of 1.5dB maximum loss for the cable itself.
An acceptable cable:
•has less than 1.5dB loss for the run length needed,
•has a characteristic impedance of 50ohms,
•has double braid screens or has foil and braid screen.
Once the cable run length is known, a cable type with low enough loss per
meter that meets the above requirements can be chosen. Longer runs
require lower loss cable.
The following table is a guide to the maximum usable lengths of some
common cable types. Actual cable loss varies between manufacturers.
There are many variants, and the table is based on typical data. Use it as a
guide only and refer to the manufacturer’s data sheet for your specific
chosen cable for accurate values.

When routing the cable:
•Route the cable away from sources of heat
•Route the cable wiring away from potential interference sources such
as ignition wiring, 400Hz generators, fluorescent lighting and electric
motors
•Allow a minimum separation of 300mm from an ADF antenna cable
•Keep the cable run as short as possible
•Avoid routing the cable around tight bends
•Avoid kinking the cable, even temporarily, during installation
•Secure the cable so that it cannot interfere with other systems
