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

No external voltage supply needed
Easy to install – mounting clamp include
Featuring a a dual-stage LNA with a mid-section SAW filter, the TW141 is a rugged waterproof, low cost, low noise, 40dB gain in-line amplifier, specially designed to boost weak signals across the full GNSS frequency, including L-band, while maintaining low antenna noise figures.
The TW141 passes DC directly from input to output to support centre conductor DC supply to the antenna, and so avoids the need for an additional bias source or bias “T”. It is enclosed in a robust weatherproof cylindrical nickel-plated brass housing (IP67 compliant) and is available with SMA and TNC female connectors.
Bandwidth: 1150 – 1750 MHz
Supply Volts: 4.75 – 10 V
Gain: 40 dB
Current: 25 mA typ.
