JCG402LR-1

Antennas RF Overview

The JCG402LR-1 is an RF whip antenna manufactured by JC Antenna, designed for operation within the 868 MHz ISM band. It features a flexible whip design with linear polarization and a gain of 2 dBi at zenith. The antenna operates with a bandwidth of 10 MHz centered at 868±5 MHz and maintains a VSWR of less than 2.0. It has a nominal impedance of 50 Ω and utilizes an SMA male connector for mount installation.

Antennas RF Feature Summary

• Flexible whip construction for adaptable mounting
• Linear polarization optimized for zenith coverage
• SMA male connector interface for secure attachment

Antennas RF Applications

• LoRa communication systems in the 868 MHz band
• Sigfox network devices operating in the ISM band
• Industrial wireless sensor nodes requiring compact antennas

Antennas RF Procurement Notes

Verify the specific connector type and cable length requirements against system schematics before ordering. Confirm that the 50 Ω impedance matches the transceiver output. Ensure the SMA male connector orientation aligns with the device housing constraints to prevent mechanical interference during assembly.

Antennas RF Selection Notes

Select this model when a low-profile, flexible antenna solution is required for 868 MHz applications. The 2 dBi gain is suitable for short-range or line-of-sight links. Consider the flexible nature of the whip for environments where rigid mounts are impractical or space is limited.

Antennas RF Part Context

This component belongs to the JCG series of RF antennas from JC Antenna, which specializes in ISM band solutions. The JCG402LR-1 is distinct from the JCG402LR-2, which operates across a broader 868-915 MHz range with higher gain. This part is specifically tuned for the European 868 MHz frequency allocation.

Antennas RF Replacement Considerations

The JCG402LR-2 serves as a related alternative but covers 868-915 MHz with 3.0 dBi gain. Verify frequency compatibility if replacing in existing designs, as the JCG402LR-1 is strictly optimized for 868 MHz.
