Of course not, Roy. I sure hope what I wrote did not suggest otherwise.
But I am trying to learn exactly which properties of an antenna system
cause house wiring to be "loaded up."

In particular, I am trying to establish whether a top-loaded vertical
with the same wire geometry and RF ground as the open-wire transmission
line-fed dipole would be just as likely to cause undesirable coupling to
the house wiring. It seems to me that it is. If it is not, I'm trying to
understand why not.

In other words, is the problem transmission line unbalance, or simply
having a radiator with undesirable proximity to house wiring?

One more way to word the question: if you tie the open-wire lines
together at the tuner/transmitter and feed the antenna as a vertical,
all of the current in the line will be common-mode. Would that be less
likely to cause undesirable coupling than the exact same antenna with
transmission line unbalance.

I am not advocating unbalanced transmission lines, verticals, or the
pursuit of radiation patterns one knows in advance to be undesirable.

I apologize for my prolix and obtuse approach, but I'm not sure how to
pose the question properly. I'll try to work on that.

Thanks again.

So here is my main question: do we object to the vertical radiation
per se (i.e., if we wanted vertically polarized radiation, we would
have put up a vertical in the first place), or is radiation from an
unbalanced line somehow more insidious in that it causes other
problems that "ordinary" verticals do not cause? In other words, why
do we really care about imbalance?

Would you intentionally load up your house wiring an use it as an antenna?
