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

The TW141 is a rugged, waterproof wideband 40dB gain in-line amplifier, specially designed to boost weak frequency signals from 1200 to 1750 MHz, including L-Band and all GNSS (GPS, GLONASS and Galileo) signals.

The TW141 passes DC supply from input to output to support centre conductor DC supply to the antenna, therefore not requiring an additional Bias source and a bias-T.


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