The Lowrance Point-1 NMEA 2000 GPS Antenna, B&G ZG100 GPS Antenna and Simrad GS25 GPS Antenna are unlike any other position-only antennas, in that they provide Heading for accurate Boat direction at any speed and radar/chart overlay.

To be able to achieve this, they contain a very sensitive electronic Compass in the housing. Therefore, it is important to ensure they are mounted in the correct position, at least 1m away from anything that emits a magnetic field i.e. Trolling motors, VHF antennas, and radars.

Like all GPS antennas, they should be mounted with a clear, unobstructed view of the sky in order to ensure quality signals from the satellites. The guide below shows the optumum positioning for your Antenna.

The Mounting Template is able to be printed out and used as a guide when drilling for your GPS Antenna, once you have determined the best position.

For more information on your Antenna, check out the Lowrance FAQs which apply to the B&G and Simrad models also, or do not hesitate to contact CH Smith Marine in store or online.
