TW120 25 dB GPS L1 In-line Amplifier
The TW120 by Tallysman Wireless is a rugged waterproof, low cost, low noise, low power, narrow band 25dB gain in-line amplifier, specially designed to tightly filter and boost weak GPS L1 signals, while maintaining low antenna noise figures. The TW120 provides for much longer cable runs from antenna to receiver, for applications such as mast-mount, roof-top and large vehicle installations, without any degradation of system sensitivity.
The TW120 passes DC directly from input to output to support centre conductor DC supply to the antenna, and so avoiding the need for an additional bias source or bias “T”.
