Product Description The 3G/4G/LTE Omni-Directional Antenna is a high-performance external signal booster designed to significantly improve data speeds and signal stability for cellular devices. With a powerful 35dBi gain rating, this antenna covers a wide frequency spectrum from 700MHz to 2700MHz, making it compatible with all major global carriers for 4G LTE, 3G, and GSM networks. It comes equipped with a 3-meter RG174 extended cable and a standard SMA Male connector, allowing for flexible placement in areas with better reception, such as near windows or outside vehicle cabins. The omni-directional radiation pattern ensures consistent signal capture from all directions without the need for precise alignment, making it perfect for IoT gateways, industrial routers, and mobile hotspots.

Key Features

  • High 35dBi Signal Gain: Significantly boosts weak signals in remote areas, enhancing download speeds and reducing latency for 4G/LTE devices.

  • Wideband Compatibility: Supports a broad frequency range (700-2700MHz) covering LTE, 3G, HSPA+, and GSM bands.

  • Omni-Directional Pattern: Receives and transmits signals from 360 degrees, eliminating the hassle of pointing the antenna toward a specific cell tower.

  • Extended 3-Meter Cable: The long-reach RG174 cable allows for optimal positioning of the antenna away from interference-heavy electronics.

  • Versatile Mounting: Features a magnetic suction base for quick and secure attachment to metallic surfaces like vehicle roofs or outdoor enclosures.

Technical Details

  • Connector Type: Standard SMA Male (Inner thread with center pin) suitable for most industrial routers and 4G modems.

  • VSWR Optimization: Maintained at ≤1.5 to ensure maximum power transfer and minimal signal reflection.

  • Vertical Polarization: Aligned with standard cellular tower transmissions for peak efficiency in urban and rural settings.

  • RG174 Coaxial Cable: Low-loss shielded cable ensures that the signal gain is preserved over the 3-meter distance.

  • Radiation Efficiency: Designed for uniform radiation, ensuring no "dead spots" in signal reception.

  • Rugged Housing: Constructed from UV-resistant ABS plastic to withstand outdoor exposure and varying weather conditions.

  • Operating Temperature: Reliable performance from -40°C to +80°C, suitable for extreme industrial environments.

  • Compact Form Factor: The sleek, low-profile design allows for discreet installation on vehicles or inside smart cabinets.

  • Impedance Matching: Precision-tuned 50 Ohm impedance for seamless integration with standard RF hardware.

  • Dual-Band Support: Capable of handling both high-frequency (2.1GHz-2.7GHz) and low-frequency (700MHz-900MHz) cellular bands.

  • Power Handling: Rated for up to 50W, making it robust enough for high-power industrial transmitters.

  • Plug-and-Play: No software installation required; simply screw onto the SMA female port of your cellular device.

  • LTE Support: Optimized for MIMO systems when used in pairs for high-speed 4G LTE-Advanced networks.

  • EMI Shielding: Internal construction is designed to minimize interference from nearby WiFi or Bluetooth signals.

  • Lightweight Build: Weighing only 65g, it puts minimal mechanical stress on the connector ports of portable equipment.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: This antenna is a passive RF component and does not require power. If you are using it with a 9V battery-powered 4G module (like SIM7600), ensure your module's internal regulator is providing the correct 3.3V/3.8V to the RF stage to make use of the boosted signal.

  • 18650 Cell: For portable IoT trackers, a single 18650 cell can power the modem, while this antenna ensures the connection remains stable even in "shadow areas" or metal enclosures where internal antennas fail.

  • IC & Capacitor Tip: If using this with a high-power GSM/LTE module, ensure you have a 1000uF low-ESR capacitor near the module's power input. The improved signal from the antenna can cause the module to draw higher peak current during transmission bursts.

  • Related Products: We recommend pairing this with our SIM7600G-H 4G Modules, SMA to IPEX/U.FL Adapters, and Industrial 4G Routers for robust field connectivity.
