Method for improving isolation of an antenna mounted on a structure

A method for improving the electric isolation of a wide coverage antenna (14) mounted on a structure (10). The structure (10) defines a peripheral wall (24) and a first longitudinal end wall (18) and the generally elongated antenna (14) has a base (40). The antenna (14) mounts on the structure (10) in a spaced apart relationship relative to the peripheral wall (24) in a direction pointing generally outwardly therefrom with the antenna base (40) being in a step back relationship relative to the first end wall (18) such that the antenna (14) is at least partially electrically isolated by the structure (10) while being substantially hidden from the first end wall (18). A second antenna (16) similarly positioned relative to the peripheral wall (24) and the first end wall (18) can be generally opposed to the first antenna (14) about the structure (10) such that the two antennas (14,16) are at least partially electrically isolated from one another.
