Dingyao - Model DY-AJ5596V -High-Precision Five Element Anti-Jam Antenna
Applicable Frequency Band: BDS B1/B3; GPS L1/L2; GLONASS L1. Product Usage: 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 an anti-jam satellite receiver to provide navigation and positioning services for the system in strong jamming environments.
- This antenna includes 4 anti-jam units and a high-precision unit, providing two major functions: high-precision positioning and anti-jam.
- The array consists of five elements, including four BDS B3 anti-jam units and one high-precision unit.
- High precision unit phase center accuracy is high.
