As PCMM said above I have questions about the choice of RF connectors too.
Why use an SMA connector for the AIS antenna when a SO239 to take a PL259 would be more normal?
Ditto the BNC for a GPS antenna. BNC is not normally used for GPS frequencies (although theoretically it can be). A SMA would be more commonly used for a GPS antenna.
To me the connectors are the wrong way around. If BNC must be used put it on the AIS antenna connection as BNC/PL259 adapters are common and cheap but SMA/PL259 adapters are more specialised and more expensive.
