Garmin DGPS 53 User manual

DGPS 53, GBR 23 and GA 23
When you need the best in position
accuracy, rely on GARMIN differential
antennas. Packaged in a waterproof
housing, these receivers and antennas
look great on any boat. They’re easy
to install and require no RF grounding.
The DGPS 53 is a powerful 12-channel
GPS receiver and antenna with an auto-
tuning differential beacon receiver. It’s
perfect for integrating with chartplotters,
radar and personal computers. The GBR 23
is a remote, auto-tuning differential beacon
receiver with built-in H-field antenna.The
GA 23 is an H-field beacon antenna with
no receiver. These units give you position
accuracy from one to five meters.
