TCA920 choke Ring Antenna

TCA930 choke Ring Antenna

APEKS TCA930 Choke Ring Antenna is a high performanceGNSS antenna for base station that covers full frequencysatellite signal tracking of GPS,GLONASS, GALILEO, BDS,QZSSIRNSS and SBAS correction service. The 2D Choke RingAntenna with strong multipath suppression performance thatspecifically designed for applications as land and marinesurveying,channel surveying,earthquake and landslidemonitoring,deformation monitoring, and wharf containeroperations that require absolute positioning accuracy andmulti-constellation support.

High Phase Center Stability

The unique 2D choke ring design of TCA930 ensures an excellent multipath reductionperformance across all GNSS frequency bands including L-Band. And the antenna featuresthe patented multi-point feeding technology to achieve greater phase center stability andhence effectively improve measurement accuracy. lt is ideal for applications of CORS stations.bridge and building deformation monitoring or geological monitoring due to its sub.millimeter phase center stability.

Track in challenging Environments

The strong ability to receive low elevation signals with high gain and wide beam width makes TCA930 an excellent choice for tracking visible satellites and provide stable and precision CNSS data under complex environments, such as obstructed environment of tree lines orconstruction.

Strong Anti-interference Performance

The antenna LNA features an excellent out-of-band rejection performance, which can suppressthe EMl, providing the stability and reliability of GNss signals. Also, it effectively avoidsdisconnection dangerous when receivers are being interfered by wireless communicationsystems, for example power grid, communication base station or radio modem applications.

More Ruggedized for Long Lasting Durability

The TCA903 cover is made of GFRP material and is structurally strong and reliable. The newlydesigned choke rings are treated with a more robust double treatment for longer lastingdurability in harsh environments. The lP67 ruggedized cover is also designed for addedprotection for inside antenna avoid from dust and water. The antenna MTBF is over 30000hours, which ensures long-time outdoor operation in challenging environments of high lowtemperature, high humidity and high salt fog.
