TW2712 features a customizable high performance, dual-feed, wide band patch element. Its Low Noise Amplifier (LNA) configuration provides a LNA for each feed, a mid section mid-section Surface Acoustic Wave (SAW) filter for the combined signal, followed by a final stage of LNA. This configuration provides excellent axial ratio that is constant across the full frequency band.
Also included with the TW2712 is an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.
TW2712 is housed in an industrial grade, weather proof housing. In addition to this it can be surface mounted using magnets, screws or adhesive material.
The non prefiltered version is the TW2710.
