There are several approaches for this. But if you have a class A

If you can and will install the system yourself (only pay for material)
it is probably cheaper to get a separate antenna for your AIS.

But if someone is going to install it for you the extra antenna will
probably
be more costly than the filter, as the filter requires less work.

There is NO "Filter" that you can purchase, reasonably, that will allow
AIS, and DSC to share an antenna. There are connection schemes that
would allow for a, DSC Receive only, and an AIS Receive only, system
to share an antenna, with with a 3db loss in the passive coupler.
Both DSC and AIS are designed for Transponder Operation, where
information Packets are transmitted as well.

Very FEW folks, who read this newsgroup, are going to be able to afford
a Class A DSC System. Most folks would find the installation of another
VHF antenna much easyier to accomplish than just about any other idea.
