ANT-GSM5WM RF Antenna Equivalent & Substitute Parts

Part Overview

The ANT-GSM5WM is an active RF antenna manufactured by RF Solutions, designed for dual-band cellular applications operating at 892MHz and 1.8GHz. This whip-style antenna provides 5dB gain across the GSM frequency bands (824MHz ~ 960MHz and 1.8GHz) with a straight configuration and bracket mount installation. The product is currently active in inventory with 1058 units in stock and maintains full RoHS3 and REACH compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved within the specified frequency ranges, termination types, and mounting configurations. Alternative models may be required due to inventory availability, lead time considerations, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ANT-GSM5WM is determined by the following critical parameters:

Frequency Coverage: The substitute part must support the primary frequency bands of 824MHz ~ 960MHz (GSM 850/900) and 1.8GHz (GSM 1800/1900). Extended frequency coverage beyond these bands does not disqualify a substitute if the primary bands are fully contained within the substitute's frequency range.

Termination Type: The substitute must feature SMA Male termination to ensure direct connector compatibility with existing RF circuits and cabling.

Mounting Configuration: The substitute must support bracket mount installation to maintain mechanical compatibility with the host system.

RF Family/Standard: The substitute must operate within the Cellular RF family standard to ensure application compatibility with GSM and related cellular protocols.

Compliance Status: Both the main part and substitute must maintain active product status and equivalent regulatory compliance (RoHS3, REACH, ECCN EAR99).

The substitute part G30.B.108111.WM from Taoglas Limited meets these substitution criteria through overlapping frequency coverage, identical termination and mounting specifications, and equivalent compliance certifications.

Engineering Selection Recommendations

Primary Substitution: G30.B.108111.WM

The Taoglas Limited G30.B.108111.WM qualifies as a direct substitute for the ANT-GSM5WM based on the following engineering criteria:

Frequency Compatibility: The G30.B.108111.WM frequency range of 698MHz ~ 960MHz fully encompasses the ANT-GSM5WM primary band of 824MHz ~ 960MHz. The substitute's 1.71GHz ~ 2.17GHz range covers the 1.8GHz band requirement. Extended coverage at 2.5GHz ~ 2.8GHz provides additional capability without compromising GSM operation.

Connector and Mounting Equivalence: Both parts feature SMA Male termination and bracket mount configuration, ensuring mechanical and electrical interface compatibility.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, meeting identical regulatory requirements.

Product Status: Both parts are active products with current inventory availability (ANT-GSM5WM: 1058 units; G30.B.108111.WM: 1315 units).

Performance Considerations: The substitute exhibits lower gain (3.2dBi versus 5dB) and different antenna geometry (dome versus whip). The substitute includes IP67 ingress protection and integrated 1m cable, providing enhanced environmental sealing. The reduced physical height (48mm versus 250mm) may present space advantages in constrained installations.

Frequently Asked Questions (FAQ)

Q: Can the G30.B.108111.WM directly replace the ANT-GSM5WM in existing GSM applications?

A: Yes. Both parts feature identical SMA Male termination and bracket mount configuration. The substitute's frequency range fully contains the required 824MHz ~ 960MHz and 1.8GHz bands. Both maintain equivalent RoHS3 and REACH compliance.

Q: What are the key differences between these two antennas?

A: The ANT-GSM5WM is a 250mm whip antenna with 5dB gain and 1.5 VSWR. The G30.B.108111.WM is a 48mm dome antenna with 3.2dBi gain, IP67 protection, and integrated 1m cable. The substitute supports additional frequency bands (2.5GHz ~ 2.8GHz) and multiple cellular standards beyond GSM.

Q: Does the lower gain of the substitute affect GSM performance?

A: Gain difference must be evaluated within the specific system link budget. The ANT-GSM5WM provides 5dB gain; the G30.B.108111.WM provides 3.2dBi gain. System performance depends on transmit power, receiver sensitivity, and path loss characteristics. Verify compatibility with your specific RF circuit design.

Q: What is the impact of the different antenna types (whip versus dome)?

A: Whip antennas (ANT-GSM5WM) provide omnidirectional radiation patterns with vertical orientation. Dome antennas (G30.B.108111.WM) provide hemispherical coverage with lower profile. Selection depends on installation geometry, space constraints, and desired radiation pattern.

Q: Are there packaging differences between these parts?

A: The ANT-GSM5WM is supplied in bulk packaging. The G30.B.108111.WM is supplied in bag packaging. Both are suitable for production integration; verify packaging requirements for your assembly process.

Q: Does the G30.B.108111.WM's IP67 rating provide advantages?

A: IP67 ingress protection indicates dust-tight and water-resistant design (immersion to 1 meter for 30 minutes). This specification is not provided for the ANT-GSM5WM. If environmental sealing is required, the substitute offers this capability.

Q: Can both antennas operate at 1.8GHz?

A: Yes. The ANT-GSM5WM operates at 1.8GHz center frequency. The G30.B.108111.WM operates across 1.71GHz ~ 2.17GHz, which includes 1.8GHz operation.
