Product overview

The Archimedes Innovation AI-4L1 anti-jamming GNSS antenna receives B1/L1 band signals and delivers four channels after anti-jamming processing. Designed primarily for low-cost vehicle platforms and small UAV applications, it suppresses wideband, narrowband, multi-tone, single-tone, sweep, and pulse interference at B1/L1 frequencies. Single jammer resistance is ≤105dB, while triple jammer resistance is ≤95dB. Antenna output power is -55~-70dBm.

The gray antenna measures 100×100×26 mm and incorporates a J30J-9ZK power supply and I/O connector alongside an SMA-K RF output. Its electrical input range is +9~32V, with +12V as the default, and power consumption is less than 8W. The X1 connector provides power input, ground, and RS422 receive and transmit connections. Operating temperature is -40℃ ~ +85℃, and storage temperature is -55℃ ~ +85℃.
