JCM072

Antennas RF Overview

The JCM072 is a multi-function shark fin antenna manufactured by JC Antenna, designed for vehicular integration. It supports GNSS and LTE applications with a maximum height of 69.10mm. The unit operates at an impedance of 50Ω and utilizes linear polarization. Key frequency ranges include 698-960MHz and 1710-2690MHz for LTE functions. The V.S.W.R. is specified as less than 3.0, ensuring efficient signal transmission. The device achieves a gain of 3.5dBi at zenith. It complies with RoHS3 standards and exhibits moisture sensitivity characteristics typical for electronic components.

Antennas RF Procurement Notes

Verify the specific ordering suffix to confirm exact frequency band coverage and connector type, as variations may exist within the product line. Ensure compatibility with vehicle roof curvature and mounting hardware requirements. Confirm RoHS3 compliance documentation is included with the shipment. Check moisture sensitivity level ratings if storage conditions prior to assembly are critical. Validate that the received unit matches the requested GNSS and LTE specifications before installation.

Antennas RF Selection Notes

Select this component when a combined GNSS and LTE solution is required for automotive platforms. The shark fin profile offers aerodynamic advantages over traditional whip antennas. Consider the 69.10mm height constraint for vehicles with limited clearance. The 50Ω impedance ensures standard compatibility with most RF front-end modules. Evaluate the 3.5dBi gain performance against specific link budget requirements for the intended LTE bands.
