The dual-system single-frequency mushroom-head timing antenna is an outdoor antenna specifically designed for high-precision time synchronization. It supports BeiDou (B1) and GPS (L1) dual-system single-frequency signal reception, ensuring timing stability and reliability. Featuring a mushroom-shaped radome, it incorporates a high-gain ceramic radiating element and a low-noise amplifier (LNA) to effectively enhance signal reception sensitivity and suppress multipath interference. With right-hand circular polarization (RHCP) and a stable phase center, it is well-suited for harsh environments.
