Aeronautical broadband communication is enhanced by providing an apparatus having a first antenna configured to communicate using a signal orientation corresponding to a first polarization, and a second antenna configured to communicate using a signal orientation corresponding to a second polarization, where the second polarization has at least one characteristic difference from the first polarization. Additional antennas may be used, where multiple antennas share one polarization, and multiple other antennas share a different polarization, and signals from like-polarized antennas are combined for beam-formation.
