Professional Hi Z Amplifier for Software Defined Radio Loop Antennas with High Impedance Amplifier and Built-in 600mAh Lithium-ion Battery

High Impedance: The impedance generated by LC resonance is also very high, allowing this amplifier to be directly connected to an LC resonant antenna to directly obtain energy from the resonant antenna, resulting in higher gain and frequency selectivity. LC resonant antennas include donut antennas, magnetic bar antennas, etc.
Application: A high-impedance amplifier is a type of impedance conversion device that converts high impedance to a standard 50-ohm output impedance, playing a role in impedance matching and isolation. It is mainly used for receiving matching of passive antennas and is suitable for donut resonant antennas, tie rod antennas, whip antennas, magnetic rod antennas, etc.
Improved Performance: With higher input impedance, more energy can be obtained from the input antenna, reducing signal energy loss caused by the unstable impedance of the input antenna and significantly improving reception performance.
Parameters: The high-impedance amplifier has an input impedance of 1MΩ, an output impedance of 50Ω, a gain of 0dB, and a bandwidth of 300MHz. It has a built-in 600mAh lithium-ion battery for long-term use.
Compatibility: Can be used with any radio receiver such as software-defined radio, Malachite, small loop antennas, donut antennas, mini loops, radio antennas, tuning loops, and other models.
