SMWG-310 (UHF, WiFi, GNSS)

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


The SMWG-310 is a compact public-safety vehicle antenna that combines a dedicated UHF path, dual-band Wi-Fi, and active GNSS in one roof-mounted unit.

Key Features

  • Handles UHF voice-radio service from 450–470 MHz at up to 30 W.
  • Keeps dual-band Wi-Fi independent from the UHF connection.
  • Adds active GNSS for navigation and vehicle tracking.
  • Preserves roof space by consolidating three functions in one IP67-rated mount.

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

Product Description

Voice, Data, and Positioning. One Public-Safety Antenna.

The SMWG-310 combines UHF communications, wireless data, and active GNSS in one compact antenna for public-safety and fleet vehicles. The three dedicated connections reduce separate roof-mounted antenna units while keeping each radio function independent.

Dedicated UHF Communications: The 450–470 MHz element provides 2 dBi gain and handles up to 30 W for compatible UHF mobile-radio equipment.

Independent Dual-Band Wi-Fi: A separate Wi-Fi element covers 2.4–2.5 and 4.9–6.0 GHz for onboard access and compatible public-safety data networks.

Active GNSS Positioning: GNSS adds navigation and tracking without consuming either the UHF or Wi-Fi connection.

Compact Protected Installation: The IP67-rated UV-resistant ASA housing consolidates all three functions in one stud mount and routes them through dedicated 15-foot cables.

The SMWG-310 keeps UHF, Wi-Fi, and GNSS organized in one vehicle installation when roof space must remain available for other equipment.

Ideal Applications

  • Public-safety vehicles
  • UHF mobile-radio systems
  • Onboard Wi-Fi networks
  • Fleet communications
  • Vehicle navigation and tracking
