The MONO-A0084 tactical HF active whip monopole antenna is designed for deployment on open ground or permanent installation and includes a deployable groundplane. The antennas’ radiation pattern is suitable for medium to long range HF monitoring. This antenna uses an operational amplifier as the active component of the antenna which operates from 9 kHz to 30 MHz.
The product features a passive bypass mode which comes into operation when the antenna is powered down. In this mode, the active matching and amplification circuitry is bypassed and the antenna operates as a completely passive receiving antenna.
