Manual abstract:
7 Installation Mounting the Antenna Mounting the Antenna The Interface Setup Page may be selected from the Main Menu on the GPS 12/ 12XL/48. For additional instructions, see the owner's manual for your GPS receiver. The supplied antenna coupler fits a standard 1-inch antenna mount (not included). Like the receiver, the antenna should be placed away from all sources of interference. As a general rule, mount the antenna at least three feet from all other antennas and the vessel's electrical system components (alternator/ignition system). Position the antenna so that the clearest view in all directions is obtained. The antenna coupler is supplied with 30 feet of RG58 cable attached. When routing the cable to the GBR 21, observe the same precautions followed when choosing mounting locations for the receiver and the antenna: Avoid routing the cable near the vessel's alternator or ignition system components. A ground strap is attached to the antenna coupler, except on the GA 22/23 H-field antennas. For proper operation, the ground strap must be connected to a vessel (earth) ground. Do not ground the coupler to the electrical system. If the coupler is not adequately grounded, the beacon signal may be too weak for the GBR 21 to provide reliable correction data. Note: The GA 22/23 H-field antennas do not require grounding. Secure the antenna mount at the desired mounting location. Thread the antenna coupler/GA 23 onto the antenna mount and hand tighten until snug. Do not over tighten. Thread whip antenna onto coupler. Connect the antenna coupler's ground strap to a vessel (earth) ground. A ground connection can usually be made by connecting to a thru-hull fitting, engine block, dynaplate or body of a metal vehicle. From the Interface Page, select `RTCM/NMEA' and `NMEA 0183 2. 0' to properly communicate with the GBR 21. Route the antenna cable to the GBR 21...
