JCA211

Overview

The JCA211 is a GPS active antenna manufactured by JC Antenna, designed for precise positioning applications. It operates at a center frequency of 1575.42±3MHz with a bandwidth of CF±5MHz. The component features right-hand circular polarization (RHCP) and provides a zenith gain of 2dBic. It includes an integrated 3-meter RG174 cable for connectivity. The unit supports GLONASS systems and maintains a 50-ohm impedance. It is rated for outdoor use with IP65-66 ingress protection standards.

Feature Summary

• Active GNSS reception capability supporting GPS and GLONASS constellations
• Integrated low-loss coaxial cabling for simplified installation
• Robust environmental sealing suitable for exterior mounting

Applications

• Automotive fleet management tracking systems
• Outdoor navigation and positioning devices
• GNSS receiver integration requiring external signal acquisition

Procurement Notes

Verify the specific ordering suffix to confirm cable length and connector type, as variations may exist within the product line. Ensure compatibility with the receiving equipment's impedance and voltage requirements before deployment. Confirm that the RHCP polarization matches the system design specifications to maintain optimal signal integrity during procurement and assembly processes.

Selection Notes

Select this model when active amplification is required for weak satellite signals in challenging environments. The integrated cable reduces installation complexity compared to discrete antenna modules. Consider the physical dimensions and mounting options, such as magnetic or adhesive bases, to ensure secure placement on vehicles or fixed structures without compromising signal performance.
