The high-precision full-band mushroom-head timing antenna is an outdoor antenna specifically designed for accurate time synchronization. It supports full-band signal reception from systems such as BeiDou and GPS, making it suitable for high-precision timing applications.
The antenna adopts a high-gain ceramic radiating element and a low-noise amplifier (LNA) to effectively enhance weak signal reception and suppress multipath interference, ensuring stable phase center performance. Its right-hand circular polarization (RHCP) design further improves anti-interference capability, making it ideal for applications with stringent timing requirements, such as communication base stations, power systems, and rail transit.
