    GA30 - DV is the latest launch of the single stage of the low noise amplifier, its technical characteristics are as follows

    1. Digital display gain: LED digital display, clearly display the current amplifier gain,

    2. Touch-tone gain adjustment: through the upper and lower key, you can adjust the gain when needed;

    3. Power control: toggle the power switch, easy control power supply state .

    Covers the GPs, Galileo, and GLONASS, Beidou 2 etc. The device features 30d gain and a noise fure less than 3dB. Since the product consumes less than20mA. the device can be placed in ine with the receiver antenna and can be powered by the GPs receiver's antenna voltaoe outout.

    The GA30-DV is More practical than any competitive product in the market.
