I have been working on an original design that i created from reviewing many Moxon style antennas :
The Moxon antenna is a simple two-element directional antenna that is typically made with tubing or copper pipe but may also be made with wire: https://en.wikipedia.org/wiki/Moxon_antenna
While not officially a Tunstile antenna : https://en.wikipedia.org/wiki/Turnstile_antenna
It does combine both the turnstile look with the dual Moxon approach.
In the design of a Moxon antenna, typically there is a radiator as one element and the other element is a reflector, however In my version the element opposite the radiator can be either open as a typical Moxon element to serve as a director, or can be active to serve as a radiator (when switching directions), or can be grounded to serve as a reflector or counterpoise to the active element.
this is one of the other ones :
here is Leonardo's J-pole copper pipe antenna :
notice that in this example the feed is to the tuning section and NOT to the main radiator.
although there are claims that it makes no difference, common sense is that the connector should be reversed and that the feed is into the longer main element, not the stub !
and here is my other copper pipe antenna :
