Personally, in my private cogitation space, where I don't have to prove
anything to anybody, I've gotten a good bit disbelieving of the various mental
simplifications of ground.
Not at all convinced any more that the ground underneath a coax shield laying
above necessarily does anything to the current on the shield if connected.
For all I know, the capacity of the shield to the ground on one side of a
blocking device, and reverse on the other side, allows the rf to "walk around"
That's much the same as driving on the shoulder to get around a wreck blocking
the pavement. I get slowed down, but I still get where I was going.
