ANT-GSMSTUB4

Antennas RF Overview

The ANT-GSMSTUB4 is a miniature quad-band GSM antenna manufactured by RF Solutions. It operates across the 900, 1800, 1900, and 2170 MHz frequency bands, supporting standard GSM communication protocols. The component features an active gain rating of +3 to +4 dBi, ensuring reliable signal transmission in compact applications. Designed with a stubby physical form factor, it utilizes an SMA connector for interface compatibility. This omni-directional whip antenna is engineered for space-constrained installations where moderate gain and broad band coverage are required.

Antennas RF Procurement Notes

Verify the specific datasheet version for the ANT-GSMSTUB4 to confirm mechanical dimensions and connector polarity. Ensure the host device supports the SMA interface type. Cross-reference the operating temperature range against the intended deployment environment. Confirm that the quad-band frequency support aligns with regional GSM network requirements. Validate compliance certifications if the application involves regulated markets.

Antennas RF Selection Notes

Select this model when a low-profile antenna is necessary for GSM-only or multi-band GSM applications. The stubby form factor suits tight internal spaces compared to full-length whips. Consider the +3 to +4 dBi gain as sufficient for short-range or line-of-sight scenarios. Verify that the SMA connector matches the existing cable assembly. Evaluate if the specific 2170 MHz inclusion is necessary for the target network infrastructure.

Antennas RF Part Context

This component belongs to the RF Solutions antenna portfolio, specifically designed for cellular communication modules. It complements modem units like the GSM-4GLTEGPS by providing the necessary RF front-end connectivity. The product line focuses on robust, compact antennas for embedded systems.
