The present invention is an integrated antenna assembly which allows for integration of a first radio system and a second radio system with the integrated antenna assembly. The integrated antenna assembly may include a coupler for providing sufficient isolation between the first radio system (ex.—a vertical polarization system) and the second radio system (ex.—a horizontal polarization system). The integrated antenna assembly may further include a common mode choke connected between a first antenna element and a second antenna element of the integrated antenna assembly. The coupler may produce a common mode based on signals received from the vertical polarization system and may also produce a differential mode based on signals received from the horizontal polarization system. The common mode choke may be configured for: preventing transmission of common mode currents from the first antenna element to the second antenna element; and being transparent to differential mode current flow.
