   Boom Length = 1.48 m.  Boom dia = 15mm x 15mm (square).

    All Element dia = 12mm.  Driven Element = Folded Dipole

     This Yagi should not need a balun as it will resonate
                        under it's own merit.

The above design has not just been drawn by myself, I have constructed this
antenna a number of times & it WILL work and a V.S.W.R of less than 1 to 1.2
can be achieved.
