The WILM antenna is side mounted on the tower. Such a mount often causes deep nulls in the transmitted pattern, but usually not 40 db.
The WILM antenna is circularly polarized, which means that there is as much vertically polarized signal as H-pol signal. When side mounted, the nulls caused by the tower are different between H-pol and V-pol. That suggests that twisting your antenna so that the elements are diagonal (45 degrees) may offer a solution that you can try. You'd loose 3 db on signals that are only H-pol and pick up much more than that if there is a V-pol signal in the air at your house.
