Overview
Ideal for applications such as mast-mount, roof-top and large vehicle installations, the TW127 GPS 25dB inline RF amplifier from Tallysman provides for much longer cable runs from any Upper band GNSS antenna (L1, G1, E, B1) to their receiver, with low current and voltage requirements.
Featuring a a dual-stage LNA with a mid-section SAW filter, the TW127 is a rugged waterproof, low cost, low noise, 28dB gain in-line amplifier, specially designed to tightly filter and boost weak signals across the upper GNSS bands, while maintaining low antenna noise figures.
The standard model offers low current consumption and DC pass through which allows both the antenna and the TW127 inline amplifier to be powered by the GNSS receiver without additional hardware such as bias-T, power cable and power supply. The TW127 is optionally available without DC Pass-through.
