Any time you double-illuminate the far field you are creating lobes and
nulls. A single omnidirectional radiator is optimal for a moving
station, unless you have means to steer the lobes whilst steering the
vehicle.

They do look bad-ass, but just connect one of them and you'll have
better overall performance (theoretically).


You could phase them for favoring the direction of travel, I suppose.
That might be the idea.
