Are you going to contend that dipoles don't work in city circumstances as

Gee, I thought I made my point quite clearly at the very beginning of
this thread. Perhaps you should re-read it. Indeed, I observed that a
true dipole (defined by most textbooks as a CENTER FED antenna -- that
is, two equal lengths) is a far better choice, because it can be choked
effectively.
The problem is that the Windom is badly unbalanced, the feedline picks
up noise, and it needs a serious common mode choke at the feedpoint to
kill the noise. But because it is so badly unbalanced, there is a lot of
common mode voltage across the choke, and a choke is likely to fry with
high power.
There's an extensive discussion of this in my Power Point on Coaxial
Chokes. http://k9yc.com/publish.htm
