I was wondering whether it might produce a narrower pattern in the front, or a deeper null off the back, or maybe even both. But indications from two people who have either modeled it or built it are that it requires 3 load resistors, one in each leg, and produces a highly reactive antenna with only a slight increase in gain. Clearly better and simpler to add a second antenna and connect them through a phasing device to null the unwanted stations, as described by Mark Connelly, WA1ION.
