hi i have read in one of the old ARRL books about a hula hoop antenna that
only stands about 3 inches high on 10 mters but works like a full size
dipole has anyone built one and if so how did it work
many thanks

Well, the first part is correct- the DDRR, but as far as working as well as
a full length dipole- that remains in the realm of the marketing folks.

Not to mention that unless you remotely tune the capacitor it is very narrow
banded.

What capacitor? Writeup in 1968 handbook doesn't show one.

The one that is needed to tune the antenna if you want to operate it over
much more than a few Kc on 80 or 40 meters without cutting or finding a way
to make the antenna longer.
