Overview

The TW3101 single band GNSS antenna from Tallysman has no magnetic properties and is specially designed to be used in close proximity with compass based instruments.

Ideal for professional precision tracking and timing applications the TW3101 provides excellent circular polarized signal reception, great multi-path and out-of-band signal rejection.

The TW3101 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 TW3101 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 TW3101 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.
