Removing the GPS Antenna

You can remove the antenna to use an external antenna. After the

antenna is removed, the BNC connector is exposed and ready for use

with an external antenna. For information on connecting an external

antenna to the GPSMAP 496, refer to the installation instructions

that came with the antenna.

To remove the GPS antenna:

1. Remove the external power cable from the connector on the

back of the GPSMAP 496.

2. Rotate the antenna to approximately a seven o’clock

position. The alignment notches in the casing must line up

with the notches on the antenna.
