ANT-2HEL28-SMA

Antennas RF Overview

The ANT-2HEL28-SMA is a helical WiFi antenna manufactured by RF Solutions, designed for operation within the 2.4GHz to 2.5GHz frequency range. It features an SMA male connector and provides a gain of 1.5dBi. The component supports a maximum input power of 50W and maintains a Voltage Standing Wave Ratio (VSWR) of less than 1.7. It operates effectively within a temperature range of -30°C to +80°C and utilizes a 50-ohm impedance system.

Antennas RF Feature Summary

• Helical physical structure optimized for compact integration
• SMA male connector interface for direct attachment
• High power handling capability up to 50W
• Wide operational temperature tolerance

Antennas RF Applications

• WiFi network infrastructure equipment
• Wireless communication modules requiring UHF band connectivity
• Embedded IoT devices with external antenna requirements

Antennas RF Procurement Notes

Verify that the SMA connector polarity matches the receiving port configuration before installation. Confirm that the operating environment remains within the specified -30°C to +80°C thermal limits to ensure consistent performance. Ensure the connected system impedance aligns with the 50-ohm specification to minimize signal reflection and maintain the required VSWR threshold during operation.

Antennas RF Selection Notes

Select this model when a low-profile helical design is required for 2.4GHz to 2.5GHz applications. It is suitable for systems needing robust power handling at 50W without compromising signal integrity. Consider this option for deployments where extreme temperature variations are expected, as it maintains stability across a broad thermal spectrum while providing reliable omnidirectional coverage.

Antennas RF Part Context

This component belongs to the RF Solutions antenna portfolio, specifically targeting wireless data transmission needs. It serves as a specialized passive RF device engineered to enhance signal reception and transmission efficiency in crowded frequency bands. The helical geometry distinguishes it from standard whip or dipole variants, offering structural advantages for space-constrained electronic assemblies.

Antennas RF Replacement Considerations

Direct substitutes must match the 2.4GHz–2.5GHz frequency range, SMA male connector type, and 50-ohm impedance. Verify equivalent gain and VSWR specifications to ensure comparable signal performance. Helical antennas with identical mounting interfaces and power ratings are the primary candidates for functional replacement.
