The Zepp antenna is a 1/2WL monopole with no counterpoise.

Here are some comments by W8JI about the need for some kind of r-f
ground or counterpoise on Zepps and other end-fed ham antennas.

Nobody said the Zepp antenna is free of common-
mode currents. The wire connected to the antenna
obviously carries current while the floating wire
just as obviously carries no current at the open
end. Radiation from the series stub just didn't
matter with the Zeppelin airships.

W8JI is a competant engineer and well versed in "traditional"
antenna design but he is not without fault or error since
he is a human being. It is very worthwhile to read what
he has to say but if it doesn't agree on your thoughts
developed from first principles then you can't use the
info until the error is resolved. That is just like
reading a book without exercising discretion with
respect to the source.
