87B             161.975         AIS - Universal Shipborne Automatic Identification System
88B             162.025         AIS - Universal Shipborne Automatic Identification System

Vessels transmit alternately on those two channels.  These are part of
the normal marine VHF band, so a normal VHF antenna is suitable.

The common SR161 receiver automatically switches between those
channels, while the SR162 monitors both channels simultaneously.
