16 Antenna Considerations
The ADL170 and ADL180 contain an internal Iridium and GPS antenna. This is a
directional antenna. The device has to lie approximately flat as shown below to get
good view of the sky. We recommend placing the device on the glare shield as shown.
Do not place the device upside down or satellite reception will be very poor.
Only the ADL180 has got a connection for the separate ADS-B antenna. A suction cup
antenna as shown below is usually supplied with the ADL180. It is intended to be
attached to the front window as shown. Please note the ADS-B antenna is very
sensitive to other electronics so try to keep it at least 15-20cm away from other devices
including the ADL180 itself. Putting the ADS-B antenna directly on the ADL180 will
result in very poor performance.

As an alternative to the suction cup antenna a glue on antenna as shown below can be
used. We recommend fitting it as shown below.
