Enhance Your Receiver or Transponders Performance
With more and more yachts fitting AIS receivers and transponders, it
makes sense to use a VHF antenna that’s up to the job. AIS systems
actually utilise a frequency of around 162 MHz whereas traditional
VHF operates at 156 MHz. The difference does not sound
significant, but the use of a dedicated, tuned AIS antenna will greatly
enhance performance of both receivers and transponders.
Digital Yacht America has just launched the AA10 antenna which is
specifically designed to operate with AIS systems. It is a white
quarter wave whip antenna which measures just 21 inches. It is
designed to fit a standard, one inch GPS antenna style mounting, so
it can be fitted on to the pushpit rail, mast top or wheel house roof
allowing for all possible installations. It comes complete with a 33ft cable which is fitted with a neat solder-less
connector, no thicker than the wire itself, so that you do not have to drill a great big hole through bulk heads in the boat
when running the cable.
The AA10 antenna costs $65 and is available from Digital Yacht America. For further information please call 978 277

Notes for editors:
AIS is a system used for vessel tracking, identity and anti-collision purposes. It is a mandatory requirement for all vessels
over 300 tonnes to carry an AIS class A transponder. This device sends the vessel's position, course, speed and identity
over VHF frequencies to other vessels equipped with either an AIS transponder or receiver. The data can then be
displayed graphically on either a dedicated device or on to a chart plotter and alarms can be activated to warn of any
potential collision danger.
Smaller commercial vessels and leisure users can take advantage of the benefits of AIS by installing a lower cost, class B
transponder, or even just a receiver to pick up the AIS transmissions. There is also an increasing use of AIS on static
navigation structures such as buoys and lighthouses (ATONS - aids to navigation) which allow navigators to positively
identify a target. One of the benefits of AIS technology is that the target is positively identified with its position, name,
call sign, MMSI number, course and speed. Chart plotters can instantly calculate closest point of approach and time to
closest point of approach and activate an alarm where necessary. Digital Yacht has published a range of White Papers
on the AIS system which are available free-of-charge on the website.
