GNSS Antenna Installation
This section provides information about planning and installing a GNSS antenna.
Planning the Antenna Location
Prior to installing the antenna, you should plan the site, antenna location, grounding
scheme, cable route, and all other details.
Locating the Antenna
Use
as a guide to locate the antenna.
Figure C-5. Locating the GNSS Antenna
Warning
: The SyncServer S6x0 GNSS interface uses the electrical
current it supplies to power a GNSS antenna to determine whether or
not the antenna is properly connected and functional. If the
SyncServer S6x0 does not detect any current, it will assume a failed
GNSS antenna and will consequently generate an alarm and switch
to another timing (non-GNSS) source.
Some GNSS splitters can block the DC current, and if used with
SyncServer S6x0, will cause the alarm condition described above.
Usage of such GNSS splitters with the SyncServer S6x0 will require
the installation of a 50 OHM load so that the SyncServer S6x0 GNSS
interface is able to detect current and operate normally.
