Jamming and interference, whether intentional or unintentional, can severely degrade GPS positioning, navigation, and timing availability, potentially leading to total signal loss. Ordinary GNSS antennas may be disrupted and unable to operate normally in complex jamming and interference environments. Therefore, specialized antennas are necessary to enhance the reception quality of desired signals and reject interference from unwanted signals to ensure receivers operate correctly.
Anti-Jamming Antenna with Superior Anti-Interference
JH001, JH002, and JH003 models are advanced GNSS antennas engineered with superior anti-interference capabilities, delivering significantly enhanced performance compared to standard antennas in environments with mild to moderate interference. Incorporating beamforming, pre-multiple filtering, and polarization suppression techniques, The antennas provide superior out-of-band signal rejection and exceptional multipath signal suppression.
