Tallysman TW125B Low current / Low Voltage In-Line Amplifier

The TW125B by Tallysman Wireless is a low cost, rugged, waterproof, low noise, low current / low voltage, 1.2 to 1.8 GHz band, 27dB gain in-line amplifier, specially designed to amplify all GNSS frequency signals, from GPS L2 to GLONASS L1. The TW125B provides for much longer cable runs from antenna to receiver, for applications such as mast-mount, large vehicle and timing systems, without degradation of system sensitivity.
Its low loading allows for both the antenna and the TW125B in-line amplifier to be powered by the GNSS receiver. The TW125B passes DC supply to the antenna, therefore not requiring additional hardware such as bias-T, power cable and power supply.
We recommend the The TW125B as a replacement for the TW126 that has been discontinued by the manufacturer.
