Hi Bill,

I phased two Pennants as ZS5K in Durban.  Seemed to work very well, although 
my spacing was less than optimum.

If you phase broadside, optimum spacing is just over 300 ft, fed in phase, 
of course.

If they are end fire, you should feed them out of phase to put nulls off the 
sides, thus reducing the width of the forward lobe.
