- MAC G4 laptop with 512MB

- Smart Radio VHF Antenna Splitter
<both can be seen on http://www.milltechmarine.com/products.htm>
- Keyspan RS-232 to USB converter
To remove the need for an additional Keyspan box, I ran the NMEA data from my other instruments (GPS etc) at 4800 baud into the SR-161 AIS box which does an exact pass through, combines the NMEA data with the AIS data, and transmits it all at 38400 baud.
The most difficult part was building the cable for a AIS, NMEA, Keyspan box connection.
So you can use a splitter with an existing masthead VHF antenna? Any downsides?
