For installation details for your external antenna,
refer to the documentation that accompanied the
antenna.
Note:
• The Beidou GNSS is supported but not currently
available.
• A GA150 must be connected in order to receive
the Beidou system when it becomes available.
• A software update will be required to add
support for Beidou once the system is available.
Please check with your Raymarine dealer for
further details.
Antenna cable length
The GA150 is supplied with a fitted 10 m (33 ft.)
cable. The length of the antenna cable can be
extended if required.
The antenna cable length can be extended by up to
10 m (33 ft.) giving a total maximum cable length
of 20 m (66 ft.)
50 ohm coaxial cable and reliable connectors
(offering protection against water ingress) must be
used when extending the antenna cable.
Note: Extending the cable length by more than
the recommended maximum length will result in
signal degradation.
