Overview
Ideal for timing, mobile, precision and military applications the TW3442 single band pre-filtered GNSS antenna provides truly circular response over its entire bandwidth thereby producing excellent multi-path and out-of-band signal rejection.
TW3442 antenna features a dual-feed wide-band patch element, with a three-stage Low Noise Amplifier (LNA), and provides an excellent axial ratio that is constant across the full frequency, superb phase linear response and tight phase centre variation.
The LNA also includes a pre-filter to enhance protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.
The TW3442 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.
To minimize performance impact from signal jamming threats, the TW3442 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.
