The Em-trak GPS antenna add-on for your Em-trak AIS and provides a faster time to first acquisition and provides a more reliable GPS position than utilising the built-in GPS receiver in the AIS itself.
This Em-trak GPS antenna is a requirement if fitting your Em-trak AIS to a steel vessel or where the mounting location of the AIS may impair GPS reception.
When programming your AIS for the first time please use the GPS antenna location on your boat as the point of reference when calculating the size of your vessel to ensure the best accuracy possible.
Includes 10m of lead and TNC connectors. The GPS antenna mounts to any standard 1 1/4″ UNC thread as found for VHF antenna mounts. These can be purchased from Whitworths.
