Not THAT hard, given that the choice of spots will be rather limited.
You can hide it on the deck of a freighter, but you'll find the
available spots on a container ship are somewhat more limited.

To everybody who knows that the antenna would have to have clear view
of the sky. Lots of space available on a tanker, much less space
available on a container carrier. And the crew will know where it is -
as it's one of the few spots where they MUST NOT paint. The crew can be
forced to reveal such locations.

Logical thinking. Sorry, I forgot that you don't understand that.
