Part of the Alaris Antennas product range

This is a wideband wire cone monopole antenna that operates over the 1 to 30 MHz band with a VSWR of less than 2.6:1 over the band, with the typical value close to 1.7:1. The antenna gives a superior radiation pattern for HF signal interception and communications. The antenna deploys from a compact enclosure by means of a combination of a winch mechanism and pneumatic actuation 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 frequency selective 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 compressor, winch, guy ropes, matching unit etc. are all included with the product.
