Fafeicy Active Mini-Whip SDR Antenna for Shortwave Radio Communication, Compact System 10 kHz to 30 MHz Portable

Wideband Reception: The frequency range covers 10 KHz to 30 MHz, capable of receiving various signals including medium wave and short wave, meeting your listening needs for broadcasts on different frequency bands. Low Power Consumption Design: The operating voltage range is 9-15V, with a current consumption of only 90mA. Low Output Impedance: The output impedance is only 50mΩ, which is easy to match with various receiving devices, ensuring effective signal transmission. Transformerless Coupling: By adopting transformerless wideband receiver coupling technology, it achieves signal reception over a wider frequency band, reduces signal loss, and enhances reception sensitivity. Double-sided Shielding: Both sides of the circuit board are shielded to effectively isolate external electromagnetic interference, improve the signal-to-noise ratio, and ensure clear and stable received signals.
