Well, it seems that most of Linux is ad hoc and naive, but sometimes it
gives you what you need :-) (not in this case btw, a Linux expert more
experienced than me wasn't able to make the card work under Linux even
after several days of work, that's why I want to use NetBSD).

In our country we have a regulation dictating that a wireless device
like this shall look from any direction like an isotropic source of
radiation with total power not exceeding ... (some value that I don't
remember; 100 mW maybe?) so if we focus the output by means of a
parabollic antenna, we must lower the power accordingly.

That's a good news! Thanks.
