Wideband HF High-Power Antenna System


This is a wideband wire cone monopole antenna that operates over the 1 to 30 MHz band with a VSWR of less than 2.8:1 over the band. The antenna gives a superior radiation pattern for HF signal interception and has been optimized for HF communication. The antenna deploys from a compact enclosure by means of a winch mechanism in less than 220 seconds by a team of as few as 2 people. The antenna can be stowed just as quickly. The antenna is equipped with a sophisticated wideband matching unit which provides excellent VSWR characteristics for best possible efficiency across the band and requires no band switching or other matching control. The design has taken into account the worst-case soil-types and so will work for diverse deployments in deserts, urban areas and wetlands. A groundplane structure of the size of a 20 foot container or larger is suggested for use. All accessories such as matching unit, controller unit etc. are all included with the product.
