JCA208

Antennas RF Overview

The JCA208 is a professional-grade GNSS surveying antenna designed for high-accuracy positioning across multiple satellite systems. It supports GPS L1/L2/L5, GLONASS G1/G2/G3, Compass B1/B2/B3, and Galileo frequencies. The device features a peak gain of ≥4dBi and an impedance of 50Ω. Technical specifications include a phase center error of ±2mm and a horizontal coverage angle of 360°. Constructed as a dome-style unit with TNC-K screw mount, it enables full-band RTK surveying applications.

Antennas RF Procurement Notes

Verify the specific ordering suffix to confirm interface type and mounting configuration. Ensure compatibility with existing receiver equipment regarding impedance and connector standards. Confirm that the required frequency bands align with regional satellite navigation system availability. Check physical dimensions against installation space constraints prior to purchase.

Antennas RF Selection Notes

Select this model when multi-frequency, multi-constellation support is required for professional surveying accuracy. The 50Ω impedance and TNC-K connector are standard for many GNSS receivers. Consider the ±2mm phase center error tolerance for high-precision geometric requirements. Evaluate the dome design suitability for the intended environmental exposure conditions.
