It is an 0mni-directional horizontally polarized system. Typical use is for disaster and rapid deployment scenarios. Its strong NVIS (Near Vertical Incidence Skywave) capabilities allow for communications over mountainous/jungle terrain and its full 2-30 Mhz spectrum broadband coverage makes it an excellent antenna for ALE operations without the need for a tuner/coupler.
