TW141 1200 to 1750 MHz 40 dB Inline Amplifier
The TW141 by Tallysman Wireless 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 provides for much longer cable runs from antenna to receiver without degradation of system sensitivity, for applications such as mast-mount, large vehicle and timing systems.
The TW141 passes DC directly from input to output to support centre conductor DC supply to the 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.
