TW3710/TW3712 Single Band GNSS Antenna

Description

Overview

Ideal for high-accuracy applications the TW3710 provides truly circular response over its entire bandwidth thereby producing excellent multi-path and out-of-band signal rejection.

TW3710 antennas features a dual-feed wide-band patch element, with a two stage Low Noise Amplifier (LNA), comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage.

The TW3710 provides excellent axial ratio that is constant across the full frequency band along with a superb phase linear response and tight phase centre variation.

The TW3710 is housed in a permanent mount industrial grade weather-proof enclosure, available in conical or flat radome styles and in grey or white colours. Two options for pole mounting are available an L-Bracket or a Pipe Mount. A 100mm ground plane is recommended for non-roof-top installations.

LNA Pre-filter Available
If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, the alternative TW3712 provides these additional benefits with an LNA pre-filter. Click here to learn more about the TW3712.
