Has anyone used or tried an antenna like this ?

Called a loop fed yagi. It is mostly a VHF beam where the driven element is
a loop. The loop is flat with the boom so it looks similar to an extra
element with the ends joined.

There is an example of a 5 element 50 mhz beam. It takes about the same
ammount of aluminum to make a 6 element beam. Would this antenna be more of
an advantage over a 6 element beam of say the K1FO type ?
