Overview

The TW125B is a low cost, rugged, waterproof, low noise, low current/low voltage, 1 to 2 GHz band, 27 dB gain in-line amplifier, specially designed to amplify all GNSS frequency signals, from GPS L5 to GLONASS G1. The TW125B provides for much longer cable runs from antenna to receiver, for applications such as mastmount, 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.

IMPORTANT: Amplifiers are directional and must be installed in the orientation indicated on the product label. (Arrow points away from antenna).
