Description

A small GPS aerial that works remarkably well
 
  • Measures just 38mm x 50mm x 17mm
  • Active device - needs 3 to 5 volts DC
  • IP67 water protection
  • 3 metres RG174 cable to SMA male
  • Directional high gain (28dBi) device
  • CE and FC approved
These small antennas really work well, provided that a satellite signal is present they will provide good reception of GPS signals. They are tuned to 1575.42MHz, the frequency of the GPS signal transmitted by satellites using the GPS system. They are a highly directional antenna with a gain of +28dBi. High gain antennas work well for satellite reception as the transmitters are always from one direction only - the sky. 28dB is the optimum ideal as higher gain will mean a narrower reception cone and hence a more limited view of the available satellites - it is a compromise between seeing sufficient satellites for a good fix (minimum of 4) and signal strength. They are compact, being just 38 x 48 x 17mm and have 3 metres RG174 cable terminated to an SMA male connector to match the GPS connection on many of the Onwa plotters and similar devices. Has a magnetic base and although this is a quite weak magnet, keep it 1 metre from a steering compass. Will magnetically attach to the top left of an Onwa KP25, KP27,KP38 or KP39 case.

The antennas give surprisingly good results even in a sheltered position – if the satellite signal is present then these antennas will work fine. A note of caution: we don't recommend these for use with our Onwa KS200A AIS Black Boxes unless the antenna is on deck or there there is a way of checking the quality of the satellites received. With an Onwa plotter with its built in satellite signal strength meter this isn't a problem but with a KS-200A Black Box there may be no way of knowing if the reception is good or bad. If the Puck aerial is mounted on deck with an open view of the sky then it will be fine but if down below be cautious.

IP67 water protected and manufactured to conform to CE, FC and SGS requirements.


You may need one of these if your equipment has a BNC  type aerial connection
