Antenna reception theory

Interesting. Assuming a plane wave sweeping broadside, with the field
being the same at every point along the wire, one might be inclined to
argue that the voltage induced on a wire should be the same at every
point along a finite length. The "rise" in voltage as the field sweeps
past would be with respect to time, rather than with respect to
position. Sort of explains why a radio receiver works just fine with
only one wire attached when you think about it. ;-)
The Earth's (static) electric field is about 120 V/m at ground level on
a stormless day. Better not walk too fast. Jogging might be fatal!
