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
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.
