Tallysman TW120

Tallysman TW120
Обеспечивает передачу ГНСС сигнала в диапазоне частот: L1, E1 и B1. Идеально подходит для крепления на мачте или крыше.


Ideal for applications such as mast-mount, roof-top and large vehicle installations, the TW120 provides for much longer cable runs from GPS/QZSS L1, Galileo E1, and BeiDou B1 antennas to their receiver.


Very low noise

Wide input voltage range, 3 to 12 VDC

Powered via antenna coax from receiver

50 Ohm port impedance

Cylindrical nickel-plated brass, IP67 compliant housing

Gold-plated connectors

RoHS 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

Maintains low antenna LNA noise figure

Easy to install – mounting clamp include


The TW120 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 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”. A clip for mounting is also available.


Bandwidth: 1555 – 1590 MHz

Supply Volts: 2.7 – 10 V

Gain: 25 dB

Current: 15 mA typ.
