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?

I assume you could have unidirectional and bidirectional capability.
Depends on lengths of the parasitic elements and proximity to driven
element.
As for circular polarity - I have to admit my ignorance of that subject and
decline comment.
