Tony,

Sometimes things get lost in all the traffic on debatable topics.

You do realize there is very little disadvantage to just going up over the 
wall and back down? It does not change the effective height any amount that 
means anything, nor does it cause a shadow. It adds a little series 
inductance, depending on the wavelength of the closed stub you form.

If you simply split the wire into two spread out wires far enough apart (a 
few wall thickness apart) you cut the small series inductance in half.

It is often too easy and too common to forget the difference between 
something we could ever notice even if we looked, and something that 
actually matters. Usually as long as we don't do something wrong, many of 
the things long discussions make sound worrisome are really insignificant.

I looked at the radials in a model, and the change on 160 from your wall 
height and thickness was very minor, and could be made "very minor over N" 
by adding multiple over-the-wall wires. You only added a ~3 degree long 
stub.
