Available with TNC, N-Type, or SMA connectors, TW125B amplifies GNSS frequency signals from GPS L5 (1,164 MHz) to GLONASS G1 (1,610 MHz) and beyond. This 28 dB gain, waterproof amplifier, which provides for extended cable runs from antenna to receiver without degradation of system sensitivity, passes DC supply to antenna to negate additional hardware (bias-T, power cable, power supply) needs. Loading level, adding 12 mA on circuit, allows antenna and amplifier to be powered by GNSS receiver.
