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.
