I appreciate the explanation given, but (I and maybe others) would like a 
follow-on of what is happening to this outside-of-the-shield current and how 
significant is it?

2. The current flowing on the outside of the shield must have an opposite 
current (charge) flowing somewhere.  Is it the portion of the antenna that 
is connected to the center conductor.

1. If for example, 100 watts is output but 10 watts is diverted to the 
outside, that still leaves 90 watts to the intended antenna--an 
insignificant (?) loss.

3.
