Lotsa apples vs pc-s, er, oranges stuff.

Perfect grounds vs backyard grounds

W/o waving hands too much, note you can't pump power into an antenna
unless you can set up a 'dipole moment.'  That is a '2 wire connection'
into which watts'll flow.

A vertical's ground system provides the mirror for the dipole's
missing half & hence connection between radial system & the up-going
spear will take power.  Radials try to be that 'perfect ground.'

Long wires.  For a random giz over the back yard, there's a vertical 
component & a horizontal - as in B29/36 story before. And far from
a perfect ground.

The vertical does some radiating as a dipole.  Some.  The horizontal
radiates too.  Tho modeled as a transmission line withouta gazinta-gazouta
dipole corrallary, imperfect ground unbalance produces the effect.

And you ALL buy baluns to eliminate that unbalance & prevent feed 
line radiation.

There, another blurb w/o the T-word.

I just hate proofs like this.  It's 'way more fun to cite unsupportable
oral tradition.  Legend of Sleepy Hollow.  Wreck of the Mary Deere.

Who's gonna re-open the compelling antenna wax subject?
