TW141 1200 to 1800 MHz 40 dB Inline Amplifier
The TW141 is a rugged, waterproof wideband
40dB gain in-line amplifier, specially designed toboost weak frequency signals from 1200 to 1800
MHz, including L-Band and all GNSS (GPS,GLONASS and Galileo) signals. The TW141
provides for much longer cable runs from antenna
to receiver without degradation of systemsensitivity, for applications such as mast-mount,large vehicle and timing systems.
The TW141 passes DC directly from input tooutput to support centre conductor DC supply tothe antenna, and so avoids the need for an
additional bias source or bias “T”. It is enclosed
in a robust weatherproof cylindrical nickel-plated
brass housing (IP67 compliant) and is available
with SMA and TNC female connectors.

TW141 Dimensions (mm)IMPORTANT: Amplifiers are directional andmust be installed in the orientation indicated on
the product label. (Arrow points away fromantenna)
