HF Active Monopole


The HF passive whip monopole antenna is designed for deployment on open ground or permanent installation and includes a deployable groundplane. The antenna’s radiation pattern is suitable for medium to long range HF monitoring. It can be deployed as part of either a linear or circular array and is quickly and easily deployed and stowed. The product can be rapidly deployed by two people within 30 minutes but can also be bolted to a plinth for semi-permanent installations. The antenna is intended for use in constructing DF interferometer arrays consisting of multiple MONO-A0097 antennas.
