YEMN300J1CH

Antennas RF Overview

The YEMN300J1CH is a low-profile, 3-in-1 external RF antenna designed by Quectel for multi-standard connectivity. It integrates support for two 5G bands and GNSS L1 & L5 frequencies into a single unit. The component features an SMA male connector interface and utilizes RG405 cable with a length of 300mm. Physical dimensions are specified as 103.5mm in length and 42.5mm in width. The design incorporates a screw mount mechanism for secure installation.

Antennas RF Feature Summary

• Integrates dual 5G cellular reception and combined GNSS L1/L5 positioning capabilities within a single compact housing.
• Utilizes a low-profile form factor to minimize visual impact while maintaining structural integrity for outdoor deployment.
• Employs a robust screw mount configuration to ensure stable attachment to vehicle roofs or fixed infrastructure surfaces.

Antennas RF Applications

• Vehicle telematics systems requiring simultaneous high-speed data and precise location tracking
• IoT gateways deployed in mobile or semi-mobile environments needing reliable multi-band connectivity
• Smart transportation infrastructure nodes supporting V2X communication protocols

Antennas RF Procurement Notes

Verify that the specific order matches the YEMN300J1CH part number exactly, ensuring compatibility with dual 5G and GNSS L1/L5 requirements. Confirm physical mounting constraints align with the 103.5 x 42.5mm footprint and screw mount style. Check that the 300mm RG405 cable length suits the installation distance between the module and the antenna position. Ensure the SMA male connector interfaces correctly with the host device's female port without adapter requirements.

Antennas RF Selection Notes

Select this model when applications demand integrated 5G and advanced GNSS functionality in a single external unit. Consider the low-profile design for aesthetic or aerodynamic constraints on vehicles or enclosures. Evaluate the screw mount option if vibration resistance and permanent installation are prioritized over quick-release mechanisms. Verify that the host system supports the required 5G and GNSS frequency bands compatible with this antenna's specifications.
