Think of a K9AY loop, or a Pennant antenna. They act like two close-
spaced verticals even through they have sloped wires. Both ends of
the Pennant actually have almost perfectly equal vertical response,
and look at the great difference in their slope!
Why worry about a eight-foot-end out of several hundred feet of wire
that responds to vertically polarized signals anyway?

You'd have a tough time electrostatically shielding a transformer in
any form that is even slightly useful in this application. Even that
is a waste of time at best, and can actually harm the system at
Just use separate windings, and keep the grounds isolated.
