Product Description

The SureCall High-Performance OTR Vehicle Antenna (SC-550W) provides better interior coverage and connectivity for multiple simultaneous users on all 5G and 4G LTE cellular devices, including hotspots, when paired with the Fusion2Go 3.0 or another in-vehicle signal booster kit.

The SC-550W is built with durable weather-proof components that are protected from water, dust, and the harshest road conditions while providing unrivaled cellular signal strength and connectivity at the fringe of the network and beyond.

Built for trucks, big rigs, RVs, and fleet vehicles, SC-550W is an omni-directional antenna that captures cell signal from all directions and works on all North American cellular networks. The SC-550W is the outdoor antenna included with the SureCall Fusion2Go 3.0 OTR booster kit.

Designed and tested in the USA with the highest-quality components, outstanding build quality, award-winning technologies, all-carrier compatibility, and world-class support, SC-550W is the premier large vehicle antenna for over-the-road trucks and commercial fleets.

  • Ultra-wideband antenna supports 4G LTE & 5G (617 - 2700 MHz). Compatible with all carriers, including Verizon, AT&T, Sprint, and T-Mobile.
  • Heavy-duty exterior truck antenna that mounts to any large vehicle to withstand the most rugged work conditions. Weather-proof components are made to last and protected from water, dust, and road grime.
  • The maximum gain of 3.5 dBi for improved call quality and faster data speeds throughout the most remote areas of the road when connected to a vehicle signal booster kit, like the Fusion2Go 3.0.
  • Two height options for the antenna are available with the included mast extensions, 16 inch and 32 inch. It also includes a 10 ft cable (integrated), and 5 ft extension (optional) with an attached FME-Female connector.
  • The omni-directional antenna transmits and receives signals in all directions and includes a built-in ground plane that allows for use on any surface– metal, fiberglass, wood, or plastic.

Includes 2-clamp mounting bracket and durable mounting hardware with thread-lock glue to withstand vibrations. Antenna fits 3/8 x 24 thread mount.
