You can use a fluorescent light bulb to locate the maximum electric
field. That will be at the ends of a 1/2WL dipole or at the top of
a 1/4WL monopole. I'm surprised you guys haven't ever done that.

Do you actually read other people's posts? Or, do you just react to them.
Do you know the difference between an E field (a vector field) and a
V field (a scalar field)? Do you know what a conservative field is? Is the
E field surrounding the ends of a dipole conservative, or not? If it is, (it
isn't)
then the voltages are unique, and if it isn't (it isn't) then the voltages
aren't
unique and what you get depends on how you measure it. There is a good,
abeit challenging discussion of this in Vladimir Rojansky's book
_Electromagnetic Fields and Waves_ under the heading 99. A. C.
Voltmeters. He writes about a ring, but the difficulties, it seems to me,
would apply to measuring voltage at the ends of a dipole, as well.
Whaowncha read it, Cecil, and tell us what you think.
