Are they close to 4 square? It might be that 4Sqr is messing up the pattern. Ideal situation would be to have Beverages on the front of 4 square. Detune the vertical elements if not doing so.

Side of winding that is attached to the Beverage wire should be grounded, secondary that coax is attached to should not be grounded.
