Full-band Antenna Signal Amplifier 4-Channel Signal Distributor 30kHz-650MHz 7-Band Filter Low Noise Amplifier

Introduction:
- Integrated with 4-channel antenna switch, low-noise adjustable gain amplifier, 4-channel signal output, 7-band high-order filters, independent filter pass through mode, independent amplifier on/off amplification pass through, independent amplifier gain control.
- It can serve as a central controller for switching between different antennas, with the signal strength of each connector being the same. It can be used as the most intuitive tool for audiophiles to compare and debug antennas. At the same time, it can be connected to antennas of different frequency bands and controlled by the machine, saving the trouble of plugging and unplugging feeders. It uses a dedicated signal switch, avoiding the loss caused by traditional physical metal switches due to multiple switching times.
- Independent dedicated filters can be used for different frequency bands to optimize the reception, especially when the receiving equipment itself does not have filtering or has poor filtering. Local devices can be used as external filters to avoid strong out of band signal interference in today's complex electromagnetic environment. This can effectively reduce the problem of serial broadcasting and false signals in the receiving equipment, and is conducive to discovering weak signals submerged in noise.
- Equipped with low-noise adjustable gain amplifier, choose the appropriate amplifier gain based on the gain level of different antennas, signal strength at different frequencies, and dynamic range of the receiving device. The device can adjust the amplifier gain within the range of 0-30dB or turn off the amplifier. At this time, the signal bypasses the amplifier and the filter is directly connected to the output.
- 4-Channel independent control, switching signal output, with the same signal strength for each port, can be used as a tool for audiophiles to compare the reception capabilities of different models of radios.
- Built-in 18650 lithium battery, Type-C 5V charging, with a battery life of about 100 hours, supporting external 9-12V linear power supply.
