Tallysman TW127

Tallysman TW127
Усилитель обеспечивающий гораздо более длинные кабельные трассы для передачи ГНСС сигнала «верхнего» диапазона (L1, G1, E, B1).


Ideal for applications such as mast-mount, roof-top and large vehicle installations, the TW127 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.


Very low noise

High-rejection mid-section SAW filter

Wide input voltage range, 3 to 10 VDC

Powered via antenna coax from receiver

50 Ohm port impedance

Cylindrical nickel-plated brass, IP67 compliant housing

Available SMA, TNC, and N-Type jack connectors

RoHS and REACH compliant


Improves signal response

Enables extended cable runs

Avoid installation of costly low-loss cable

Fits in-line with antenna cable

No external voltage supply needed

Easy to install – mounting clamp include


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.


Bandwidth: 1559 – 1610 MHz
