Feature：
1. Application： High resistance amplifier is a kind of impedance conversion device, which can convert the higher impedance to the standard 50 ohm output impedance, so as to play the role of impedance matching and isolation, mainly used for passive antennae reception matching, suitable for donut resonance antennae, tie rod antennae, whip antennae, magnetic rod antennae and so on.
2. Parameters： High resistance amplifier input impedance is 1M Ohm , output impedance is 50 Ohm , gain is 0dB, bandwidth is 300MHz, built in 600mAh lithium ion battery to provide long time use.
3. Compatible： Can be used for any radio receiver radio for Software Defined Radio etc, fo r malachite, for small loop antennae, for Donut antennae, for Mini Loop, radio antennae, tuning loops and other models.
4. Enhanced Performance： Higher input impedance can get as much energy as possible from the input antennae, reduce the signal energy loss caused by the unstable impedance of the input antennae, which can greatly improve the reception performance.
5. High Impedance： Since the impedance generated by LC resonance is also very high, this amplifier can be directly connected to the LC resonance antennae to obtain energy directly from the resonance antennae, which can obtain higher gain and frequency selection characteristics, LC resonance antennas including for donut antennas, magnetic bar antennas, etc.
