Product Description
The ultra-small four-element anti-jamming antenna measures only 65mm * 65mm * 19.5mm. It supports the four-element broadband anti-jamming function of the Beidou-3 B1/L1 frequency point. It can reject various broadband and narrowband jamming such as harmonics, sweep frequency, pulse, frequency modulation, phase modulation, etc.. In the B1/L1 frequency band, the antenna integrates an active anti-jamming receiving antenna, which includes core components such as an anti-jamming RF chip, intermediate frequency filter, ADC, anti-jamming digital baseband processing, and DAC.
Main Function
Satellite Signal Reception: Receive satellite signals from GPS-L1 and BDS-B1.
Jamming Rejection: It can reject various types of broadband and narrowband jamming such as harmonics, sweep frequency, pulse, frequency modulation, amplitude modulation, phase modulation, etc. for GPS-L1 and BDS-B1 frequency bands.
Software Support: Features a software online upgrade function.
