Default 80m Vertical over lossy soil

A third antenna, not discussed here, would be a real 1/4 W monopole that is
truely connected to earth ground and uses no radial conductive elements.
Here, the monopole functions as a dipole but 1/2 of the radiation pattern
exists as a mathematical image reflecting against true ground (not a good
conductor of electrons like radials, merely a zero voltage reference point).


This confused example attempts to pull together disparate
characteristics for using ground/radials by extending the problematic
metaphor of an antenna image.

It takes very little effort to answer all objections raised by this
confusion, but it takes very much effort to implement the solution to
this confusion that is the answer = push the radials out to the radio
horizon.

Anyway, the confused example has no bearing on my preceding responses;
the two, the vertical and the vee (as described) are poor performers
below 10 degrees.
