Product Overview

TA-4L1-L2 is a compact, dual-frequency 4-channel anti-jamming Antena, which is designed for civilian drones and industrial applications. It supports GPS L1 frequency signal reception and features dual-system anti-wideband interference capability, with a maximum resistance of 3 simultaneous interference sources. Internally integrated with an antenna array and anti-jamming modules it serves reliable navigation for drones, unmanned vehicles, and similar platforms, protecting user terminals from unintentional interference and malicious attacks while significantly enhancing PNT (Positioning, Navigation, and Timing) information security.

Key features include :

• GPS_L1 frequency anti-jamming functionality.

• Suppression of multiple interference types: narrowband, wideband, pulsed, sweep-frequency, and Gaussian noise interference, as well as suppression-type jamming.

Designed to ensure robust navigation performance in complex electromagnetic environments, it is ideal for scenarios requiring high-precision, interference-resistant PNT solutions.
