I always had impression from way others talk + needs 2 feed lines were x did not but both worked( vertical and horizontal mode), as well as V aka VEE was half X but gave you both polarities like X and only needed 1 feedline to have big polarities but was told and forgot which polarity lacked and other was more dominant yet best thing told about it is anyone with either a vertical or horizontal you could hear well ect. Clearing this for me if you can and benifits of the VEE aka V style beam and benifits of it as a log periodic i once drew up plans for one but never got a chance to apply my skill I just dropped out of everything now I am older and trying to get into a lot of design of again for fun.
