Product overview

The Archimedes Innovation AI-4L14L2 anti-jamming GNSS antenna is designed for low-cost vehicle-mounted applications and small UAV platforms. It receives four B1/L1 channels and four L2 channels, processes both frequency bands for interference suppression, and delivers a combined output. Suppression covers wideband, narrowband, multi-tone, single-tone, sweep and pulse interference. The antenna includes a set of high-precision L1+L2 elements to supply dual-frequency high-precision signals to the receiver. Reception bandwidths are 1568±10MHz for B1/L1 and 1227±10MHz for L2.

The gray antenna measures 130*130*40mm and weighs 550g±20g. Its J30J-9ZK power and I/O connector provides power input, ground, 232 receive and 232 transmit connections, while an SMA - K connector carries the RF output. The input range is +9~32V, with +24V as the default. Operating temperature extends from -40°C to +85°C, and storage temperature from -55°C to +85°C. Antenna output power is -50~-70dBm.
