TW141 1200 to 1750 MHz 40 dB Inline Amplifier
TW141 1200 to 1750 MHz 40 dB Inline Amplifier
The TW141 by Tallysman Wireless is a
rugged, waterproof wideband 40dB gain inline 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
