Frequency coverage: 500kHz to 30 MHz. Excellent directivity can help you reduce noise and improve signal-to-noise ratio, and can dig out weak signals that are drowned by noise when received by traditional antennas.

When used for ordinary radio reception, the shortwave effect is very obvious. When using FM, it can be used as a passive antenna and the effect is better. It can also be used as a full-band receiving antenna when used for S DR for Malachite radio reception.

Main coverage: 500kHz to 30MHz;. Listening to shortwave radio is an exciting hobby, but for city dwellers, the reception experience is often disappointing. We could barely hear any useful signals, even from relatively strong radio stations.
