Hello All, Need some thoughts from the electronic minded people.
I had a navman chartplotter
in my boat but had to upgrade it to a raymarine
A65 plotter and backbone system when the autopilot
The navman plotter had an external aerial to get the GPS
signal. The A65 raymarine
has an internal aerial but loses the satellite
signal occasionally as it is mounted inside the yacht. So loss of signal means loss of autopilot
etc. What I want to know is if all external aerials have the same operating mechanism and are they nmea
0186 or 2000 sensitive. I believe the raymarine aerial just plugs into one of the backbone connectors to get the signal to the GPS
, the navman aerial has what looks to be a 2 wire plug
So the big question can I use the navman aerial and save the $500 on an overpriced raymarine unit? Any thoughts much appreciated.
