1. An apparatus comprising:
a horizontal antenna array configured to receive or transmit electromagnetic waves;
two vertical antenna arrays installed back-to-back in or on a tail or a fin of an aircraft, each of the two vertical antenna arrays comprising:
a receiving array configured to receive electromagnetic waves; and
a transmitting array configured to transmit electromagnetic waves; and
a controller configured to select an operating antenna array from the horizontal antenna array and one of the two vertical antenna arrays based on at least:
an elevation angle between a location of the aircraft and an orbital location of a satellite,
a skew angle between the operating antenna array and the satellite,
a waveform or a throughput consideration,
a transceiver power level, and
a power spectral density (PSD) threshold allowance.
