[BC] RF fields around base of shunt fed monopole

Mike,

The problem with that is the areas near ground are the most
difficult for NEC to do accurately (and EZNEC is built on
the NEC calculating engine). Although the ASD or other office
in DC may accept the model prediction, that does not relieve
you if an EB inspector walks toward the tower with his nice 
new calibrated Narda and finds excessive public exposure 
outside the fence, or prohibited levels inside the fence
where personnel normally go while the antenna is radiating.

Thus, in this case - especially now that inductive field
measuring devices are available - I've got to go along with
Tom when he says you have to measure it to be sure you won't
be fined. You would have to check with your lawyer to see if
the calculation of the model and its acceptance might reduce
or mitigate the fine, but if you have no way of disputing the
inspector's reading and that inspector is in a mood to hang
paper on you, I think you may be stuck. 

I think this is judgmental thing with the inspector and the 
EB/DD as to how hard they push it. IOW, if you can show a clean 
calculation according to the OET standards AND can say you 
measured a day or two later with a freshly calibrated meter, 
found no violation AND invite the inspector back to measure it 
again you might be able to wriggle off the hook, but since I'm 
not a lawyer I'd run it by one before I made ant response to
a Notice of Apparent Violation.
