ANT-315-HETH

Antennas RF Overview

The ANT-315-HETH is a helical, quarter-wave embedded monopole antenna designed for through-hole mounting on printed circuit boards. Manufactured by TE Connectivity / Linx Technologies under the HE series, it operates within the 305 MHz to 325 MHz frequency range with a center frequency of 315 MHz. The component features linear polarization and a 50 Ohm impedance. It supports ISM protocols and is suitable for applications requiring reliable sub-GHz wireless communication in compact form factors.

Antennas RF Feature Summary

• Helical coil structure provides compact quarter-wave performance for embedded integration
• Through-hole termination ensures secure mechanical attachment to PCBs
• Linear polarization optimizes signal consistency for sub-GHz ISM band operations

Antennas RF Applications

• ISM band wireless sensor networks
• Remote control systems
• Security and alarm systems

Antennas RF Procurement Notes

Verify that the specific order matches the ANT-315-HETH part number to ensure correct 315 MHz operation. Confirm through-hole compatibility with your PCB layout. Check RoHS compliance status as indicated in official documentation. Ensure environmental ratings meet operational temperature requirements before deployment.

Antennas RF Selection Notes

Select this model when a low-profile, embedded solution is required for 315 MHz ISM applications. The helical design offers space efficiency compared to traditional whip antennas. Verify ground plane dimensions against datasheet reference specifications to maintain optimal electrical performance and impedance matching.

Antennas RF Part Context

This component belongs to the HE Series of embeddable antennas from TE Connectivity / Linx Technologies. The series includes variants for 418 MHz, 433 MHz, 868 MHz, and 916 MHz frequencies. All models share similar helical construction and through-hole mounting characteristics, differing primarily in resonant frequency and associated electrical parameters.

Antennas RF Replacement Considerations

Direct substitutes within the same family include ANT-418-HETH, ANT-433-HETH, ANT-868-HETH, and ANT-916-HETH. These alternatives offer identical mechanical and mounting profiles but operate at different center frequencies. Ensure the replacement matches the required frequency band for your specific application.
