The TW-A0004 is a man-portable tactical HF directional antenna system designed for rapid deployment in the field. It is ideal for highpower and long-range HF communications. The antenna system consists of a multi-wire travelling-wave antenna that gives good directivity throughout the frequency range. The TW-A0004 can be connected directly to 50 ohm transmitters without the need for an antenna matching unit. The VSWR is below 2.5:1 over the entire frequency range from 1.5 to 30 MHz and the antenna is rated for a transmitter power of 2.5 kW continuous (4 kW PEP). The TW-A0004 can be deployed by two persons in less than 60 minutes including the mast.
