The Muldipol Multiple Collinear Array concept has been specifically developed for ground-air-ground, air traffic control, and associated land or sea based communication applications.  This omnidirectional concept employs a unique method of shielding the feed cables to improve the radiation pattern characteristic.  The Muldipol also has a high degree of isolation between discrete elements within a closed space array.
