Re: Aftermarket Antenna for Raymarine Chartplotter??
One thing to watch for is how you connect to the chart plotter. I have an E80 plotter and a Raymarine GPS unit that talks to the chart plotter via sealink (I think).
The E80 has NMEA in and out but there is only one speed available. If you have AIS via NMEA then you want 38400 baud and the standard GPS units are 4800 baud and you are screwed.
I have no idea what your plotter has for inputs and outputs, I am just pointing out possible gotcha's. The previous owner of my boat hooked up the VHF to the NMEA feed from the plotter. They also hooked up the AIS. They got te AIS working but the VHF never did have position information. I am not sure if the previous owner ever noticed that little detail.
