描述

Feature: 1. High impedance amplifiers are mainly used for passive antenna reception matching, suitable for donut resonant antennas, rod antennas, whip antennas, magnetic rod antennas, etc. 2. A higher input impedance can extract as m-uch energy as possible from the input antenna, reducing the signal energy loss caused by unstable input antenna impedance and greatly improving reception performances. 3. Due to the high impedance generated by LCresonance, this amplifier can be directly connected to the LCresonant antenna, obtaining energy directly from the resonant antenna and achieving high gain and frequency selection characteristics. LCresonant antennas include donut antennas, magnetic rod antennas, etc. 4. Compact size and easy to use. 5. Built in 600mAh battery for long working time. Specification: Input impedance: 1MΩ Output impedance: 50Ω Gain: 0dB Bandwidth: 300MHz Re Charging voltage: 5V Battery: 3.7V, 600mAh Re Charging current: 600mA Working hours: >24 hours Item size: 49 x 45 x 18mm / 1.9 x 1.8 x 0.7in Item weight: 59g / 2.1ounce. Package List: 1 x High Impedance Amplifier
