Joe,

I agree. But I believe it's gain is very low mostly because it's made up of
electrically very small loops.

A very small loop has its main lobes in the plane of the loop - not
perpendicular to the plane of the loop as in a quarter-wave-on-a-side loop
in a Quad antenna. When a very small loop is mounted horizontally, there's
a null in the pattern towards the ground. So even though it's mounted
horizontally, it is less susceptible to the effects of the ground.

I also agree with Dr. Maxwell. But a very small loop mounted horizontally
is not like a big antenna mounted horizontally.

And Nick is correct - KK5JY shows a two-loop system farther on down - it's
kind of approaching a horizontal Waller Flag.
