Do you know the difference between an E field (a vector field) and a

E field surrounding the ends of a dipole conservative, or not?


Heh, heh, reminds me of the [color] box on the job applications
in the 50's. The choice was []White, []Black, []Other________.
I checked 'Other' and wrote 'tan'.

Bend the ends of a resonant dipole around close to each other and
measure the voltage with a shielded differential RF voltmeter. For
100 watts input, you will get almost 1000 volts RMS between the ends,
a far cry from the ~70 volts RMS at the center feedpoint.
