Do you have an actual application for this circularly polarized
directional UHF antenna with the "loop" included?
A simple "Turnstile" will give good CP. The satellite guys use them with
reflectors.
I can give some information about simple crossed dipole antennas that give
pretty good CP recpiton at VHF.

HR message ...
Just wondering what adding horizontal parasitics to a UHF loop does?
HR depends - but you CAN make a beam - er a directional antenna
HR like a quad driven element, and a yagi-type reflector and/or director
HR element(s).
HR it works - been done
You made me recall the cubical quad. But a single loop with yagi-style
elements added each face might have a directed beam pattern instead of
bidirectional? BTW would that work too with circular polarization?
