If fed in phase and spaced correctly, there could be gain to the front and
to the back with a decreased propogation to the sides.
This is usually desirable if traveling on a mostly straight stretch of
highway. I think the spacing is a little too far apart for use on most cars.

I like them two at a time--co-phased. Is there any gain to be had that way
or am I just skin pipe dreaming at the petro?
