TCA930

3D Choke Ring Antenna

TCA930 is a high‑performance 3D GNSS choke ring antenna engineered for professional base station use. It supports full‑frequency signal tracking across GPS, GLONASS, GALILEO, BDS, QZSS, IRNSS, SBAS and L‑Band correction services. With superior multipath suppression, it is purpose‑built for land/marine surveying, channel measurement, earthquake/landslide monitoring, deformation detection, and wharf container operations demanding absolute positioning accuracy.
 
This 3D Choke Ring Antenna delivers exceptional high phase center stability via its unique 3D choke ring structure and patented multi‑point feeding technology. It achieves submillimeter‑level repeatability to minimize measurement errors and maximize precision. This outstanding stability makes it the ideal choice for CORS stations, bridge/building deformation monitoring, geological monitoring, and other high‑accuracy mission‑critical applications.
 
It excels at signal tracking in challenging environments with high gain and wide beamwidth, ensuring reliable reception of low‑elevation satellite signals. It maintains steady tracking and outputs precise data even under tree cover, building obstructions, or complex construction conditions. Its strong anti‑interference LNA provides excellent out‑of‑band rejection to suppress EMI and prevent signal dropout from power grids, base stations, or radio modems.
 
TCA930 features a rugged GFRP housing with enhanced dual‑treatment choke rings and IP67 protection for outstanding durability. It operates reliably in harsh conditions including extreme temperatures, high humidity, and heavy salt fog. With MTBF exceeding 30,000 hours and compliance with IGS, NGS, CE, FCC, and RoHS standards, it ensures stable long‑term outdoor performance for professional GNSS applications.
