1. Power supply filtering consists of solid-state capacitors and NPO-grade MLCCs, supporting external 9-12V power supply. It also features a built-in high-capacity lithium battery for rechargeable use.
2. Filters signals from various FM antennas, such as Yagi and dipole antennas, before amplification.
3. Frequency coverage: 88-108MHz (China), extended to 50-138MHz, accommodating FM from Europe, America, Japan, and Korea, facilitating FMDX activities and AIR band reception.
4. Gain: 30dB, with a knob for continuous adjustment from 0-30dB, providing low-noise amplification.
5. Power supply: Built-in battery powered, Type-C 5V rechargeable, or external 9-12V power supply with a 5.5mm x 2.1mm connector (positive inside, negative outside), offering two power supply options for convenience.
6. Rear interface: SMA female connector; left side for ANT antenna connection, right side for RADIO audio reception.
7. It can provide high-quality signals for various radio heads (car radios that cannot be installed in cars), as well as models such as Tecsun, Sangean, and Hanrongda 6686.
8. The amplifier's functionality is guaranteed. The specific range of stations and frequencies it can receive depends on the electromagnetic environment of the area, the broadcast station's transmission angle and power, the receiving antenna, and the receiving equipment.
9. Note: This amplifier is suitable for areas with weak FM signals or for frequencies with relatively weak signals.
