The Automatic Identification System (AIS) is an automated
tracking system used on ships and by Vessel Traffic Services (VTS)
for identifying and locating vessels by electronically exchanging data
with other nearby ships and VTS stations. AIS transponders use two
different frequencies, VHF maritime channels 87B (161.975 MHz) and
88B (162.025 MHz). SCOUT has designed the KS-30 antenna to be
tuned on the AIS frequencies. Perfectly suited to the AIS radar and AIS Engine.
