Recommended For

The SureCall Fusion2Go 3.0 OTR Signal Booster Kit is the ideal solution for trucks, work vans, fleets, RVs, and other large vehicles that need the most powerful mobile signal booster available on the market for maximum connectivity, even in rural locations. Also ideal for overlanding and boondocking.

How it Works

The Fusion2Go 3.0 OTR Signal Booster Kit works by mounting the included OTR outdoor antenna to the vehicle, which then receives the outside cell signal and passes it over a cable to a signal amplifier located inside of the vehicle. The amplifier boosts the cell signal, and then sends it over another cable to the included low-profile inside antenna, which broadcasts the boosted signal to the area of the vehicle that needs better signal.

The entire process also works in reverse, so you get a strong and reliable connection back to the distant, land-based cell towers.

Estimated Inside Coverage

The strength of your existing outside signal, measured in the location where you plan to mount the outside antenna, has a direct impact on the amount of inside coverage you'll get from a signal booster. The table below shows how much coverage you may get depending on your outside signal strength:

Existing Outside Signal Strength Estimated Inside Coverage
Strong (5 Bars) Up to 6 feet from the inside antenna
Medium (3-4 Bars) A few feet from the inside antenna
Weak (1-2 Bars) 18 inches from the inside antenna
None (0 Bars) No Coverage

Please Note: It is important to remember that there are many factors that impact the size of the inside coverage area, so actual results may vary from these estimates.
