JCG402

Overview

The JCG402 is a GSM antenna manufactured by JC Antenna, designed for wireless communication applications. It operates within two primary frequency configurations: 824–894 MHz and 1710–1990 MHz, or alternatively 880–960 MHz and 1710–1990 MHz. The component features linear polarization with a zenith gain of 2 dBi and maintains a standard 50-ohm impedance. It utilizes an SMA male connector for interface connectivity.

Feature Summary

• Supports dual-band GSM frequency ranges including 824-894/1710-1990 MHz or 880-960/1710-1990 MHz
• Features linear polarization with 2 dBi zenith gain
• Equipped with a 50-ohm SMA male connector

Applications

• GSM wireless communication systems
• Alarm antennas
• IoT devices requiring GSM connectivity

Procurement Notes

Verify the specific frequency band configuration required for your application, as the JCG402 supports either the 824-894 MHz or 880-960 MHz range in addition to the 1710-1990 MHz band. Confirm connector type and polarity specifications match your system requirements before ordering.

Selection Notes

Select this model when a compact GSM antenna with 2 dBi gain is needed. Ensure compatibility with 50-ohm systems. Consider the JCG402LR-1 variant if an 868 MHz ISM band operation is required instead of standard GSM bands.

Part Context

JC Antenna specializes in RF antenna solutions for IoT and mobile communications. The JCG402 belongs to their GSM antenna lineup, offering reliable performance for cellular data transmission. Related models include the JCG402LR series for ISM band applications.

Replacement Considerations

The JCG402LR-1 serves as a functional alternative for 868 MHz ISM band applications, though it differs in frequency range. Verify mechanical dimensions and connector compatibility when substituting.
