Hi,

AIS operates on 162MHz which is in the maritime VHF band, I think. Can
I split the VHF aerial line to feed both a DSC VHF set and a stand
alone AIS receiver??? - this receiver in particular

TVMIA

NO!!!!
The VHF transmitter will burn out the AIS receiver. If it was an AIS
transceiver, it would also burn out the VHF Receiver when the AIS
transmitted.

AIS requires special wide bandwidth antennas. For receive you might get by
with a regular marine band VHF antenna, with reduced reception.
An AIS transmitter however will soon fry its output stage on a regular VHF
marine antenna as the SWR is too high. There are at least 4 antenna
manufacturers now offering AIS versions and they cost a bit more!
