Hi Richard,

I tried it. I considered my Hentenna as a transmission line and I
applied the standing wave theory according to "THE ARRL ANTENNA BOOK
18th Ed 1997, Fig 65".
The currents flow the antenna as shown below:

Obviously, the currents of the 3 parallel horizontal branches are
flowing in the same direction. Their sum gives the total field. On the
other hand, we have 3 antiparallel pairs of currents flowing through
the vertical branches. Therefore the field becomes equal to zero.
As a result, the arrangement radiates and it can not be considered as
a transmission line.
