I was researching multi-element driven array antennas when I stumbled
across the web page below. It talks about a curtain quad antenna. Is
this proven antenna design or antenna snake oil?

Hello Michael,
It isn't snake oil, but with many elements, it is difficult to get it
working in practice. Such structures are narrow band and you don't
have a single tuning point to correct something.
If you plan to build an existing antenna, make sure to make a real
good copy of it. Just a good SWR doesn't automatically mean you have
the correct current distribution to get the stated gain.
With kind regards.
