When your cellular router, modem, or communication module is trapped inside a metal cabinet or located in a low-signal area, the 3M 3G GSM Aerial Amplifier Antenna provides the reach you need for a stable connection. Designed to boost both standard GSM (2G) and 3G network signals, this high-gain antenna pulls in weak cellular frequencies to prevent dropped data packets and failed SMS messages.

The standout feature of this antenna is its generous 3-meter (nearly 10-foot) extension cable, which allows you to route the aerial outside of enclosures, out of windows, or onto higher vantage points for optimal reception. It is terminated with a standard SMA connector, making it a plug-and-play upgrade for a massive variety of industrial cellular routers and development boards.

Perfect For:

  • Industrial Enclosures: Route the antenna outside of metal control cabinets or vending machines that otherwise block internal cellular signals.

  • Vehicle & RV Connectivity: Mount the aerial to the roof of a car, truck, or RV to improve mobile hotspot and tracking module performance on the road.

  • Remote Routers & Modems: Upgrade the stock, stubby antennas on desktop cellular routers to pull in a stronger signal from distant cell towers.

Technical Specifications:

  • Network Compatibility: 2G (GSM/GPRS) and 3G (UMTS/HSPA)

  • Frequency Range: 850 / 900 / 1800 / 1900 / 2100 MHz

  • Cable Length: 3 Meters (Approx. 9.8 feet)

  • Connector Type: SMA Male (Pin with internal threads)

  • Mounting Method: Typically features a magnetic base for secure attachment to metal surfaces

  • Impedance: 50 Ohm

  • Radiation Pattern: Omnidirectional
