4 GPS ANTENNA INSTALLATION

This section contains general information as well as installation information for GPS antennas. Garmin
recommends the antennas shown in Table 4-2. However, any equivalent antenna that meets the
specifications listed in Table will work with the G5.
The G5 can receive GPS position information using the unit's internal antenna or by connecting an external
antenna. It is recommended to verify the ability of the G5 to receive GPS information via the unit's
internal antenna as GPS reception quality is dependent upon the installation. The G5 will share GPS
information with any connected GDU 37X/4XX.
The G5 can additionally receive GPS position information from a GPS 20A or
GDU 37X/4XX. A minimum of one GPS antenna is required for G5 installations receiving GPS
information from another LRU. Additional GPS antennas may be used for redundancy, but are not
required.
A GPS 20A (and connected GPS/WAAS antenna) can be used as the sole GPS source for a G5 system,
however it is recommended to also install a GPS antenna on a G5 or GDU 37X/4XX for redundancy. If
the G5's GPS receiver is not used in a particular installation, it may be disabled in configuration mode (see
Section 8.4.13).

4.1 Non-Garmin Antennas

Table 4-1 lists non-Garmin antennas currently supported by the G5. For non-Garmin antennas, follow the
manufacturer's installation instructions. It is the installer's responsibility to ensure that their choice of
antenna meets FAA standards according to the specific installation.
