Description

The LWC-GSM-MM-03 is a specialized coaxial cable assembly integrating a 4 dBi GSM antenna with a 3-meter RG58 stub. Designed for 2G/GSM frequency bands (824-960MHz and 1710-1980MHz), this assembly provides the necessary reach and impedance matching for extending cellular connectivity to remote sensors, telemetry units, or industrial modems. Its linear polarization and omnidirectional horizontal pattern (360° H, 30°/40° V) ensure reliable signal reception in varied orientations.

Constructed with anodized aluminum and standard SMA-Plug connector, the assembly offers a durable, low-cost solution for system integrators needing to fine-tune RF paths or add cable length to existing GSM setups. The RG58 cable type balances flexibility with performance, making it suitable for prototyping, field deployments, and base station accessory applications where direct antenna mounting is impractical.

Key Features

  • Extended Cable Reach: 3-meter RG58 coaxial stub enables remote antenna placement for optimal signal reception and system layout flexibility.
  • Dual-Band GSM Operation: Covers primary 2G/GSM frequency bands for global compatibility with GSM850/900 and DCS1800/PCS1900 networks.
  • Impedance Matching Stub: Facilitates RF tuning and matching for improved signal integrity and reduced VSWR in custom installations.
  • Standard SMA Interface: SMA-Plug connector ensures broad compatibility with cellular modules, routers, and test equipment.
  • Durable Construction: Anodized aluminum housing provides corrosion resistance and mechanical protection for outdoor or industrial use.
  • Omnidirectional Radiation: 360° horizontal beamwidth ensures consistent coverage regardless of orientation around the antenna axis.

Applications

  • Remote GSM Sensor Networks: Extend cellular connectivity to IoT sensors, environmental monitors, or telemetry units deployed in distant or shielded locations.
  • Industrial Telemetry & SCADA: Provide reliable 2G data links for industrial modems, RTUs, and PLCs in manufacturing, utilities, or oil & gas applications.
  • Base Station & Repeater Tuning: Use as an impedance-matching stub or extension cable for testing and optimizing GSM base station antenna systems.
  • Fleet & Asset Tracking: Enhance signal reception for GSM/GPRS trackers on vehicles, containers, or mobile assets in low-coverage areas.

Frequently Asked Questions

What frequency bands does the LWC-GSM-MM-03 antenna stub support?

The LWC-GSM-MM-03 supports dual GSM frequency bands: 824-960 MHz (GSM850/900) and 1710-1980 MHz (DCS1800/PCS1900). This covers primary 2G/GSM networks globally, making it suitable for IoT devices, remote telemetry, and backup communication links requiring standard cellular connectivity.

How do I connect this antenna stub to my GSM module or router?

Connect the SMA-Plug end of the 3-meter RG58 cable directly to the SMA female jack on your GSM module, cellular router, or modem. Ensure the connector is hand-tightened securely to maintain 50Ω impedance and minimize VSWR. For devices with other connector types (e.g., RP-SMA, TNC), use a compatible gender-changer or adapter pigtail.

Can this antenna stub be used outdoors or in harsh environments?

Yes, the anodized aluminum housing provides corrosion resistance, and the RG58 cable has a durable PVC jacket. It is suitable for outdoor or industrial environments. For permanent installations, use weatherproof tape or conduit at the connector junction to prevent moisture ingress, which can degrade VSWR and signal performance over time.

What is the purpose of the 3-meter cable stub in RF applications?

The 3-meter RG58 cable stub provides physical flexibility to position the antenna away from electronic noise sources, extends reach to optimal signal locations, and serves as an impedance-matching transmission line. In tuning applications, the stub length can help adjust the electrical length to match the source impedance, improving overall RF system efficiency and reducing standing wave ratio.
