JCN504

Overview

The JCN504 is a high-accuracy GNSS internal active antenna manufactured by JC Antenna. It operates within the frequency range of 1561.098 to 1602 MHz, supporting Right-Hand Circular Polarization (RHCP). The component provides a gain of 3dBic at zenith relative to the PCB and maintains a Voltage Standing Wave Ratio (V.S.W.R.) of less than 1.5. It features a standard 50Ω impedance, ensuring compatibility with typical RF receiver interfaces for precise positioning applications.

Feature Summary

• Designed as an internal active antenna for high-accuracy GNSS signal reception
