TACTICAL INTERFERENCE PROOF PRECISION GNSS ANTENNAS Extremely robust active antennas for GNSS (GPS, Glonass, Galileo...) navigation receivers. They utilize innovative dual quadrature feed technology with up to two stage low noise amplifiers to maximize the rejection of sub-harmonics and L-Band signals. Advantages (compared to traditional antennas) • truly circular response over the entire antenna bandwidth • superior rejection of multipath and cross polarized signals • maximum filtering against interfering signals • mechanical design attenuates signals from low elevation (horizon) B-models have in addition to A-model features a special two stage low noise amplifier and band bass filtering design in order to further attenuate all unwanted signals.
