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

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

Manufacturer: | Categories: ,

The TW126 by Tallysman Wireless is a low cost, rugged, waterproof, low noise, low power, 1.2 to 1.8 GHz band, 25dB

gain in-line amplifier, specially designed to amplify all GNSS frequency signals, from GPS L2 to GLONASS L1.



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.
