HF Active Monopole


The HF active whip monopole antenna is designed for deployment on open ground and includes fast deployable groundplane whips which attach to the antenna base. The antennas’ 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 10 minutes. The antenna is intended for use in constructing DF interferometer arrays consisting of a number of MONO-A0085 antennas
