The HF active monopole antenna is designed for mounting on vehicles and other metallic structures. 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 8 kHz to 88 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. The antenna features an integrated filter to suppress transmissions in the FM broadcast band from 88 to 107 MHz.
