Overview

Ideal for applications such as mast-mount, roof-top and large vehicle installations, the TW125B GPS 28dB inline RF amplifier provides for much longer cable runs from any GNSS antenna to their receiver, with low current and voltage requirements.

The TW125B is a rugged waterproof, low cost, low noise, low power, narrow band 28dB 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.
