Overview
The JCG821 is a GSM whip antenna manufactured by JC Antenna, designed for mobile communication applications. It operates within the frequency ranges of 824–960 MHz and 1710–2170 MHz. The antenna features linear polarization with a gain of 3.0 dBi at zenith and maintains a voltage standing wave ratio (VSWR) of less than 2.5. It has a nominal impedance of 50 ohms and includes an integrated 3-meter RG174 cable.
Feature Summary
- Whip-style design suitable for mounting via magnetic base
- Dual-band operation covering GSM and cellular frequencies
- Integrated 3-meter RG174 coaxial cable for connectivity
Applications
- Automotive communications systems
- Vehicle-mounted radio equipment
- Mobile data terminals in transportation fleets
Procurement Notes
Verify the specific connector type required for your application, as datasheets may not explicitly state the plug configuration despite mentioning the RG174 cable. Confirm that the dual-band frequency coverage aligns with local network standards. Ensure the magnetic mount surface is clean and conductive for optimal performance. Check for any regional regulatory approvals if deploying in restricted zones.
Selection Notes
Select this model when a compact, magnetically mounted solution is needed for vehicle integration. The 3-meter cable length provides flexibility for routing inside vehicles. Consider the VSWR specification to ensure efficient power transfer. This antenna is appropriate for environments where permanent installation is not feasible or desired.
Part Context
JC Antenna specializes in customized antennas for automotive and industrial communications. The JCG821 belongs to their line of GSM whip antennas, often used in fleet management and vehicle telemetry. It complements other models like the JCE605NR which supports broader connectivity including GNSS and LTE.
Replacement Considerations
No public substitute part numbers are confirmed in available documentation. Verify compatibility with existing RF connectors before considering alternatives from other manufacturers.
