Four Element Anti-Jam Antenna

Description:
Product Name: Four Element Anti-Jam Antenna
Product Model: DY-AJ4609A
Applicable Frequency Band: BDS B1; GPS L1; GLONASS L1
Product Usage:
Covering BDS B1, GPS L1, GLONASS L1 frequency points, it is widely used in military communication equipment such as command aircraft and ground mounted vehicles, especially suitable for situations with special requirements for anti-jam. This antenna array is used in conjunction with anti-jam satellite receivers and can provide navigation and positioning services for the system in strong jam environments.

Here is the transcription of the product description and main functions from the provided images: Product Description: The antenna array consists of 4 BDS B1, GPS L1, GLONASS L1 anti-jam units. The amplifier circuit has high out-of-band rejection and high linearity, ensuring that it can still work normally in the presence of strong jamming signals. Built-in voltage regulator circuit can work normally in a wide input voltage range. Main Function: Receive satellite signals from GPS-L1, BDS-B1, Glonass-L1, and Galileo-E1. It can reject various types of broadband and narrowband jamming such as harmonics, frequency sweeps, pulses, white noise, frequency modulation, amplitude modulation, and phase modulation for the GPS-L1, BDS-B1, and Glonass-L1 frequency bands.
