Abstract
A system of high-frequency (HF) antennas is disposed on various aircraft body panels. The antennas are configured for orthogonal polarization such that NVIS may be operable no matter the state of the ionosphere. The antennas are disposed on substantially perpendicular body panels so that, when operated in concert, the resulting signals have opposite polarization and at least one signal will bounce off the ionosphere.
