FAQ

Does this antenna work without a signal booster?

No. The SC-550W is designed to work with an in-vehicle signal booster such as the SureCall Fusion2Go XR. On its own, it cannot amplify or rebroadcast signal.

What’s the difference between the 16” and 32” height options?

The height determines how far the antenna extends above the vehicle cab. The 16” version is ideal for lower-profile installs or height-restricted areas. The 32” version, which uses the included mast extension, provides better line-of-sight over the cab for stronger reception in remote areas.

Is the SC-550W compatible with my vehicle’s signal booster?

It supports any booster with FME, SMA-Male, or SMB-Female connectors. Use the included adapters for universal compatibility. If your booster uses a different connector, a separate adapter may be required.
