Hi Terry
to "any part of the antenna".
This is where things get very murky.
I can see the sense in having a barrier to stop somebody grabbing a RF hot radiating element and to keep people out of the EMR danger zone, but in the case of a ground mounted vertical they will still be walking close to, and over, the radials that extend well beyond the said barrier. Often they are just laid on top of the lawn and pegged down (as mine are), draped over garden beds, along fences etc and are certainly "touchable", at least in some places.
What about a vertical mounted on the top of a steel shed which then becomes the ground plane, and by your interpretation, part of the antenna. Difficult to make the shed untouchable!
