ABSTRACT:
An antenna system is provided having a common reflector and a plurality of spaced apart end-fired yagi type elements each comprising a driver and one or more directors. The elements are positioned longitudinally parallel to each other in separate planes. Adjustable parasitic reflecting rods are located adjacent to the elements so as to cause the generation of a low energy scattering field which, in turn, increases inter-element isolation.
