Jim:

Rather than zig-zag each half of the inverted-Vee, why not make the half 
element that cannot go over the neighbor's property a T shape where the 
bottom of the vertical leg is the feed point?

Plan view where the feed point is the double dot

I think you will find it is also more broad banded than running a W shape.
