That would be true of course for his own situation, the classic RF in the
shack problem, but he specifcaly asked about interference to the local
neighborhood if you re-read his post. In that case I doubt the antenna
type
will have any significant impact.

Rf on the feedline will be radiated through the whole path, and probably
much lower and closer to the neighbor. RF on the feedline is never a good
thing.
