Wideband conical antennas such as this one are widely used in ground-air communications for omnidirectional HF transmission and reception. A special system using such an antenna was designed and installed recently at Shannon Aeradio, Ireland, by CSA (C&S Antennas Ltd.). This was, in part, for the NARTEL (North Atlantic Radio/Telephone) HF communication system used by aircraft on North Atlantic flight paths. Shannon Aeradio also comprises the communications centre for Scotland's Prestwick Airport.
