This is a yagi designed to receive VHF FM radio. Normally the driven element (the one connected to the cable) is a straightforward folded dipole because this feeds signal to 75 Ohm cable efficiently, but in this case the dipole has been distorted into a triangular shape. I really can’t think of a good reason for this, and suspect that it is just a gimmick. Incidentally, the second from the right director element has swivelled round almost to the vertical. This can happen when the fixing bolt (which goes through a hole in the boom) is not fully tightened. Over a period of years the bolt wears a slot in the boom and the element gradually twists.
