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?

Hi Michael,

Looks like the author went to a lot of trouble - with passion.

There is nothing unreasonable about the design or the results.
However, you should note these designs are highly removed from
ground's proximity which can skew many, finely tuned projects.

You should also note what is typically referred to as the decline on
return for your investment as the design gets bigger. Further, in
actual construction, you rarely obtain the mathematical precision that
is required to enjoy the forecasted results.
