At 10,000 meters, 3 meters off the ground:
E(theta) is maximum off the ends at 3.5E-8 V/m
E(phi) is maximum off the sides at 2.6E-7 V/m

This agrees with the expected horizontal polarization off
the sides, and vertical polarization off the ends.

Now what's the result without the surface wave?

Roy Lewallen, W7EL

Good point: E(theta) off the ends 1.25E-7 V/m
E(phi) off the sides 1.04E-7 V/m
