I just replaced my old VHF radio with a new Garmin VHF/AIS receiver. Also replaced a Raymarine chart plotter with Garmin MFD7610. I planned to use the existing antenna but after looking at it decided that the cable was starting to fray and the whip was showing signs of deteriorating. Replaced with a new antenna from West Marine. The VHF owners manual says connect to VHF antenna but nothing about a splitter or separate AIS or GPS antenna. Everything works fine but did not test it for any loss. It currently uses the internal GPS from the MFD. Perhaps there is some loss with this arrangement but it seems to work for me.
