TW125B

The TW125B is a low cost, rugged, waterproof, low noise, low current/low voltage, 1 to 2 GHz band, 28dB gain in-line amplifier, specially designed to amplify all GNSS frequency signals, from GPS L5 to GLONASS G1.

Features

  • Very low noise
  • Wide input voltage range
  • Gold-plated SMA, TNC or N-Type Jack connectors
  • Nickel-plated brass, IP67 compliant housing

Benefits

  • Enables extended cable runs
  • Avoids installation of costly low-loss cable
  • Fits in-line with antenna cable
  • No external voltage supply needed

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 pointing away from the antenna).
