SV-ADSB-470 Installation, Configuration, and Testing
14-6 SkyView System Installation Guide - Revision S

Record the SkyView serial port that you have chosen on each display as you will need to
configure it later for use with the SV-ADSB-470.
The SV-ADSB-470 communicates with the SkyView system using serial ports, not
SkyView Network. Thus, the SV-ADSB-470 will not be listed as a device in the list of
SkyView Network devices (such as SV-ADAHRS-200/201, SV-EMS-220/221, etc.)
This is normal.
Antenna Selection and Installation
The SV-ADSB-470 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 SV-ADSB-470. Antennas
available include (but are not limited to):

UAT Antennas

o Rami AV-74 (TSO’d):


Transponder Antennas: Any antenna suitable for use with an aircraft transponder will
work with the SV-ADSB-470.
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 SV-ADSB-470 antenna should not be installed within 2 feet (24 inches) of the
transponder antenna.
Antenna Ground Plane
When a conventional aircraft monopole antenna is used it relies on a ground plane for correct
behaviour. For ideal performance the ground plane should be very large compared to the
wavelength of reception, which is 305 mm. In a metal skinned aircraft this is usually easy to
