I noticed today that the em-trak B300 AIS transponder might not need an external antenna. They say...
"The internal high-performance GPS with advanced redundancy
is complemented by a unique internal GPS antenna which means
that in certain installations no external GPS antenna is
needed."
Any idea which "certain installations" can skip the external
antenna?
