Steve,
It looks to me like this will give you 10.5 dbi gain, 14 db f/b at an angle 
above the horizon of 30 degrees.  Using #12 wire.  

reflector length - 10.6 meter
driven ele length - 10.0 m
spacing 3.5 meter

F/b is best at 14.2.  If you want to work at 14.05 make the reflector 10.7

Gain is flat across the band.

But if you want more gain, with no f/b consider a lazy H.
