Ideal for applications such as mast-mount, roof-top and large vehicle installations, the TW125B provides for much longer cable runs from any GNSS antenna to their receiver, with low current and voltage requirements.
Low current / Low voltage
Very low noise
Wide input voltage range, 3 to 16 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
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
The TW125B is a rugged waterproof, low cost, low noise, low power, narrow band 27 dB gain in-line amplifier, specially designed to tightly filter and boost weak signals across the full GNSS bandwidth, while maintaining low antenna noise figures.
The TW125B 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: 1000 – 2000 MHz
Supply Volts: 2.7 – 10 V
Gain: 28 dB
Current: 25 mA typ.
