There was some phony antenna that when tested turned out to be nothing
but a resistor across the feed point. Google search and my fading
memory couldn't recall the name. The VSWR was great, but nothing else
about the antenna was useful, probably due to all your RF power being
dissipated in the 50 ohm load instead of being radiated by the
antenna.

A squashed rhombic with an approximately 500 ohm resistor does have
some proponents. See:

Search Google for "T2FD antenna".
