The Whiskey, or “W” antenna is designed as a local, regional to continental (0-4000km) coverage antenna intended for High Frequency Communications. 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. Radial ground plane or grounding is not required making the antenna ideal for ground/rooftop installations and mobile “on the move” field use. The “Whiskey” antenna can be purchased in transportable or permanent models.
