Overview

Ideal for professional precision tracking and timing applications the TW3100 single band GNSS antenna from Tallysman provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.

The TW3100 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 ± 10 MHz bandwidth centred on 1575.42 MHz.

The TW3100 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.

To minimize performance impact from signal jamming threats, the TW3100 is compatible with Tallysman’s Anti-Jamming add-on, which modifies the radiation pattern of the GNSS antenna to eliminate signals arriving from -10° to +15° from horizon, while slightly increasing the gain of the antenna at zenith.

If you need enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi, the alternative TW3102 provides these additional benefits with an LNA pre-filter.
