Installing the SureCall Fusion Professional is fairly simple:

  1. Install Outside Antenna.
  2. Connect to the Amplifier.
  3. Install Inside Antenna.
  4. Power on.

The most “difficult” part is installing the Yagi Antenna, which requires climbing on to the roof of your house and/or up the attic, mounting the Yagi Antenna, pointing the antenna toward your nearest cell tower, and running cable into your home.

You’ll need some general handyman skills, but nothing too specialized. Just a ladder, some general tools like a Phillips screwdriver and adjustable wrench, your smartphone, elbow grease–and you’ll be ready to go.

If you prefer having someone else do the job, you can contact your local general contractor, electrician, or anyone who’s installed a satellite TV dish.

  1. Find The Best Outside Signal: Begin by finding the best signal outside your house. This is done by walking around the perimeter of your home and either using the number of bars on your phone (ok method), smartphone apps (good method), or Field Test Mode (great method) to find the best location.
    Pro tip: Locating the side of your home getting the best signal is the MOST CRUCIAL step of the installation process.
  2. Install Yagi Antenna: The area with the best signal is where you will mount the Yagi Antenna. Place the antenna as high up as possible ideally on the roof with a mounting pole although the fascia or gable is acceptable.
  3. Connect to Amplifier: Once the Yagi Antenna is mounted, connect the included SC-400 cable to the Yagi Antenna and to the “Outside Antenna” port on the amplifier. Some run cable into the attic, others prefer using the window-entry cable. It’s all a matter of preference and aesthetics and where you want to locate the amplifier.
    Pro tip: The amplifier does all the heavy lifting for boosting signal and will get warm. Keep it in a well-ventilated area.
  4. Install the Inside Antenna: Once the cable is connected to the “Outside Antenna” port of the amplifier, do the same for the “Inside Antenna” port. Depending on which type of inside antenna you bought, you’ll want to place it either on the ceiling or wall. Dome antennas radiate signal outward in all directions and are best placed in the center of a large open space, while panel antennas shoot signal forward and are best placed on a wall facing outward. The most important point is to have the inside antenna located in the area you need signal the most.
    Pro tip: Having enough separation between the two antennas prevents oscillation. Make sure there is at least 20 feet vertical or 50 feet horizontal distance between the two.
  5. Power on: Plug in the power supply to the Amplifier and to the wall outlet. The amplifier will sync up and if you see the yellow LED come on, it’s working. Adjust the gain on your dial (keep it at maximum for best results), and check to see near the inside antenna how much better signal you’re getting.
    Pro tip: Any post-installation adjustments like relocating the Yagi Antenna will require rebooting the amplifier. Simply unplug the power supply for 5-10 seconds and replug to reboot the system.

Frequently Asked Questions

How Do You Install the Outside Antenna?

The SureCall Fusion Professional comes with a yagi directional antenna. It needs to be pointed at your source of signal, or cell tower.

We recommend placing it as high as possible on your roof. This helps reduce oscillation between the outside antenna and the indoor antenna. The antenna should be securely fastened to a pipe, mounting pole, or protrusion. Make sure your connectors are weatherproofed.

You’ll want to find your nearest cell tower and point the antenna toward it. That will gain you the largest amount of signal.

Your cable will need to be run inside your home and hooked up to the amplifier. Then, set up your indoor antenna with 20 feet of vertical or 50 feet of horizontal distance separating it from your rooftop antenna, plug in your Fusion Professional amplifier, and switch it on. You should see a significant improvement in the quality of your signal.

Please call us at 1-800-470-6777 for a free consultation and answers to any other questions you might have.

How Many Cellular Devices Can the Fusion Professional Support at One Time?

The SureCall Fusion Professional can support numerous devices. However, we tend to suggest a maximum of twenty. Should you need more, we recommend a more powerful booster, such as the SureCall Fusion 5s.

What are the differences between the Fusion4Home, Fusion Professional, and Fusion 5S?

Essentially, the differences boil down to power and features. The Fusion4Home works well in strong signal areas, the Fusion Professional can handle numerous rooms in weak signal areas and up to a whole large home or office in strong signal areas, and the Fusion5s can handle large homes even in weak signal areas.

In short: get the most powerful booster you can if you live in a weak signal area.

Does the Fusion Professional Work Inside of an Apartment or Multi-Family Housing Unit Like a Condo or Townhome?

It can. However, you will need access to your roof or elevated area to install the outside antenna. If you do not have access to this, we recommend the SureCall EZ 4G, which is optimized for apartments.

Do I Need to Contact My Carrier for the SureCall Fusion Professional to Work?

Registration with your carrier is required by FCC regulations.

Can the SureCall Fusion Professional Be Expanded With More/Stronger Antennas?

Absolutely! We recommend this in order to expand your coverage. Should you decide to buy an extra indoor antenna, you will need a splitter and extra lengths of cable in order to make use of it.

This applies to the outdoor antenna as well. Should you find that the included yagi antenna is not powerful enough for what you need, you can always upgrade it with an Ultra High Gain or LPDA antenna.

Can the Input Signal from Your Cell Phone be Password Protected?

No, you cannot protect cellular signal with a password. Everyone who enters your home or office will receive boosted signal.

How Long Can the Cable Run be Between the Amplifier and the Antennas? Is there a Difference if More (3-4 total) Indoor Antennas are Installed?

There are two pieces of information to keep in mind when talking about cable runs.

First, the shorter the better. If you can get away with a shorter run, do it.

Second, bear in mind separation between antennas. In order for your system to work as well as it can, you’ll want around 20 ft of vertical or 50 ft of horizontal separation between your indoor and outdoor antennas. This is a caveat to the above point: your cable runs should always be longer than 20 ft vertically or 50 ft horizontally between both antennas.

What is the Return Policy?

All SureCall units, including the Fusion Professional, can be returned within 60 days. It also comes with a 2 year warranty.
