Product Description

Three Core Gateway Connections. One Vehicle Antenna.

The SMWG-301 integrates cellular service, local wireless access, and active GNSS in one compact surface-mount antenna for fleet and public-safety gateways. Its three-element layout reduces separate antenna housings while keeping each function independently connected.

Wide-Area Cellular Connectivity: The cellular element covers 800–1250 and 1650–2700 MHz for compatible 4G LTE and legacy mobile equipment.

Flexible Dual-Band Wi-Fi: A separate Wi-Fi element covers 2.4–2.5 and 4.9–6.0 GHz, keeping local wireless access independent from the cellular connection.

Active GNSS Positioning: The GNSS element covers 1561, 1575, and 1602 MHz with a 26 dB LNA for navigation and tracking equipment.

Protection for Mobile Environments: The IP67-rated UV-resistant ASA housing helps keep dust and water away from internal components across vehicle installations.

The SMWG-301 provides a compact three-port option for gateways that need cellular, dual-band Wi-Fi, and GNSS without separate roof antennas.

Ideal Applications

  • Fleet-management gateways
  • Public-safety vehicles
  • Mobile data terminals
  • Vehicle telematics
  • Navigation and tracking systems
