Antennas RF datasheet and documents for ANT-4HEL28-SMA

ANT-4HEL28-SMA

Antennas RF Overview

The RF Solutions ANT-4HEL28-SMA is a compact helical antenna designed for operation within the ISM band at a primary frequency of 433 MHz. It features an SMA male connector and maintains a characteristic impedance of 50 ohms. The device exhibits a gain of 1.5 dBi and a Voltage Standing Wave Ratio (VSWR) of 1.7:1. Physically, it measures 28 mm in length with a direct mount configuration. The unit operates reliably within a temperature range of -30°C to +80°C.

Antennas RF Feature Summary

Compact helical design with rugged plastic finish
Omni-directional radiation pattern suitable for telemetry
Ready-to-operate structure requiring no tuning

Antennas RF Applications

ISM band wireless communication systems
Telemetry data transmission
RF signal reception and transmission modules

Antennas RF Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to ensure compliance with current technical specifications. Confirm that the SMA male connector gender matches the receiving equipment interface requirements. Check environmental ratings against operational conditions to ensure suitability for the intended deployment environment.

Antennas RF Selection Notes

Select this component when a low-profile, omni-directional solution is required for 433 MHz applications. The fixed 28 mm length and direct mount type make it suitable for space-constrained enclosures. Ensure the system impedance aligns with the 50 ohm specification to minimize signal reflection and maintain optimal power transfer efficiency.

Antennas RF Part Context

This model belongs to the RF Solutions helical antenna series, characterized by its stubby physical form factor. It serves as a specialized variant optimized for the 433 MHz frequency range, distinguishing itself from broader band antennas through its tuned helical geometry and integrated SMA interface for direct PCB or cable connection.
