That is correct.
The part of the open-wire quarterwave feedline closest to the Zeppelin is a voltage node.

As far as I know the zepp is a halfwave wire fed over a quarter wave transformer and NOT a quarterwave against the zeppelin frame

The Zepplin was a rigid metal frame dirigible which was used as a
counterpoise against a quarter wavelength antenna from the transmitter.
Why would one feed a high voltage source when the gas bags were filled
with explosive hydrogen?
I don't know where this Zepplin story originated. Can anyone enlighten me?

Ray,
Explore the Zep antenna used on the _Zeppelin_ [1] air ships.? Or maybe
the more moderern TACAMO setup for ELF.

So how is an end fed using? the coax transmission line modeled?? Since
the coax is two conductors, outside and inside, can the transmission
line be replaced by a single wire?
