There's actually a legal requirement for signage like this described
in the OET bulletin, and, for that matter, an ANSI standard for what
the sign should look like. A lot of the legalities would revolve
around what other access controls there are (for instance, if you had
a 12 foot high double chain link fence with razor wire around your
square mile of property where you live by yourself, you could
probably claim that incidental public exposure isn't likely, so signs
wouldn't be required)
The only problem is that such a sign might actually incur unwanted
regulatory oversight. Around here, putting up such a sign would be
tantamount to a "Please call code enforcement to harass me"
sign. The unfortunate folks putting up a small FM broadcast station
near here spent tens of thousands of dollars dealing with various and
sundry hearings (after the project was approved) because they put the
legally required signage on the perimeter fence, which went near a
popular walking, mountain biking, riding trail.
There's also the "signs as shooting targets" problem (why explosives
magazines don't have signs on their sides), but that's just a matter
of proper placement (i.e. not on the guy wire)
There are examples of signs in various places:

You'd have to decide whether the blue "notice" style signs or the
Yellow "WARNING" signs would be more effective in the tradeoff
between attracting unwanted attention vs keeping people out.
