Tallysman TW126 Mid-Power 1.2 to 1.8 GHz 25dB In-line Amplifier

TW126 Mid-Power 1.2 to 1.8 GHz 25dB In-line Amplifier

The TW126 from Tallysman has been discontinued by the manufacturer. The TW125B is a suitable replacement.



The TW126 provides for much longer cable runs from antenna to receiver, for applications such as mast-mount, large vehicle and timing systems, without degradation of system sensitivity.

The TW126 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.
