Addition to previous response that I sent. A single dipole will give you gain in the direction it is pointed. Dual dipoles at the same elevation should negate the gain, but create an omni pattern.
I've experienced narrower bandwidth mounting one on a mast. Moving the same dipole onto a tower gives it a broader bandwidth.
