Re: Aftermarket Antenna for Raymarine Chartplotter??
It does not have a built in receiver, but takes NMEA GPS data. Thus, it is not an antenna, but a complete gps receiver that you need. So any receiver that provides NMEA out may be used, you may get cheaper ones, than the Ray. You may even use cheap gps modules, just be careful, they usually work with 5V supply and signals. You need to solve this and waterproofing.
