I have read this take me back to the GPS Antenna COMPARE section.

GPS Antenna Introduction

The GPS Antenna provides your marine network with position and time data.
These are actually a combined antenna and GPS receiver. They deliver accuracy better then 3 meters by decoding Satellite Differential (SD) correction signals from the Wide Area Augmentation System (WAAS).

Installation

Mount the antenna with a clear view of the sky.

Choosing Your GPS Antenna

Since standard NMEA 0183 or NMEA 2000 communications is used, the GPS Antenna does not need to be provided by the same manufacturer as your marine network.
There are many well-made GPS Antennas available. Review the Comparison guide and choose one that meets your needs.
