Product Description

This product is our independently developed active anti-interference antenna, using 100% domestically produced materials as preferred. The antenna consists of B3, B1/L1 low noise amplifier, reflecting surface, and radome. The interfaces include RF interface and power control interface. Before leaving the factory, the whole unit undergoes high and low temperature tests, vibration tests, shock tests, and atmospheric pressure tests. The appearance and dimensions can be customized according to customer requirements.
