Should I power my splitter from the VHF or AIS?

The SP160 splitter has a fail-safe mechanism which ensures your VHF has priority at all times. This means that whenever the power is cut to the splitter, it will provide direct access for the VHF radio to the antenna. This means the AIS is essentially disconnected from the antenna. As a result, we recommend that you power the splitter from the same power source (circuit breaker, fuse, etc) as the AIS and not from the VHF.

Or alternatively, and perhaps better, approach is to keep power supplied to it at all times whenever either the VHF or the AIS has power.

    Can the splitter + AIS + VHF all be powered from the same supply?
