SMWG-305 (LTE, WiFi, GNSS)

LTE, Wi-Fi, and GNSS Surface-Mount Antenna

The SMWG-305 is a compact surface-mount antenna for fleet and public-safety gateways that need separate LTE, dual-band Wi-Fi, and GNSS connections.

Key Features

  • Maintains dedicated paths for cellular backhaul, local networking, and positioning.
  • Covers low-band and higher-frequency LTE through one cellular connection.
  • Extends Wi-Fi across 2.4 GHz and 4.9–6.0 GHz.
  • Rugged IP67-rated housing protects vehicle connectivity in wet and dusty conditions.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

LTE, Local Networking, and Positioning. One Mount.

The SMWG-305 brings the three primary connections used by many fleet and public-safety gateways into one compact surface-mount antenna. Cellular, Wi-Fi, and GNSS remain independently cabled while sharing one roof-mounted housing.

Dedicated LTE Backhaul: The cellular element covers 694–894 and 1700–2700 MHz for compatible 4G LTE and legacy mobile equipment.

Independent Dual-Band Wi-Fi: A separate element covers 2.4–2.5 and 4.9–6.0 GHz for local access and compatible higher-frequency wireless networks.

GNSS Positioning Built In: Active GNSS supplies navigation, tracking, and timing data without requiring another antenna on the vehicle roof.

Rugged Vehicle Integration: The IP67-rated UV-resistant ASA housing and dedicated 15-foot leads support protected routing to equipment installed inside the vehicle.

The SMWG-305 consolidates LTE, Wi-Fi, and GNSS when a mobile gateway needs three dedicated RF connections from one roof location.

Ideal Applications

  • Fleet-management gateways
  • Public-safety vehicles
  • Smart-highway equipment
  • Vehicle telematics
  • Mobile Wi-Fi and tracking systems
