SureCall Fusion4Home Max Signal Booster Kit

Dropped Calls? Slow Data? Spotty Signal? SureCall Says NO MORE!

The SureCall Fusion4Home Max is the most powerful signal booster in its class. It significantly enhances talk, text, and data speeds for all 4G LTE and 5G cellular devices (including hotspots) across all North American carriers in the weakest of signal environments. It shines in homes and offices anywhere – urban, suburban, and especially remote locations.

Maximum Cell Coverage Anywhere

The Fusion4Home Max will maximize coverage no matter where you are – out in the sticks or the suburbs. It amplifies cell signal at its strongest point to deliver a stronger and crisper signal indoors, more so than its competition. This is a huge benefit for remote areas. You can expect coverage in areas where other booster systems wouldn’t be able to cover.

Cover up to 6,500 sq ft* with rock solid and reliable cellular signal.

* Effective coverage area depends on quality and strength of outside cellular signal, internal building materials, and antenna configuration.

SureCall’s Cutting Edge Signal Booster Technology

If maintaining a reliable connection feels impossible, SureCall’s 2XP technology delivers twice the transmission power to reach those distant cell towers, ensuring consistent connectivity in even the weakest of signal areas. No matter how weak the signal, with Extended Range Technology (ERT), it’ll be amplified at its strongest point to achieve superior coverage and deliver quality cell signal for all cellular devices in your home or office.

The SureCall Fusion4Home Max is the only home, consumer-level signal booster kit to use an "outside amplifier. This configuration reduces the amount of signal loss you would normally see with a cable run that extends from the outside antenna to the indoor amplifier. They also provide guaranteed results with an industry best 60-day money back guarantee and 3-year manufacturer's warranty.

Quality Cellular Signal for Everyone

We offer several different Fusion4Home kits tailored to specific use cases. In general, if you live in an area with strong outside signal, the omni-directional outdoor antenna should work for you.

If your signal outside is weak, we suggest a directional or “Yagi” outdoor antenna because it delivers stronger signal to the amplifier.

Whip-style indoor antennas attach directly to the booster and radiate signal in a 360-degree radius from that point. It's the easiest to install but provides less indoor coverage than other options.

Dome antennas are best placed on an indoor ceiling and radiate signal downward in all directions, so a ceiling mount installation will work best.

Panel antennas shoot signal outward, so they’re best placed on a wall.

SureCall’s Best Performance Guarantee

SureCall is the only cell phone booster name on the market to report real coverage expectations and still overdeliver in performance. They also provide guaranteed results with a 60-day money-back guarantee and a 3-year manufacturer's warranty.

The Fusion4Home cell phone signal booster for home connects users across North America using an upgraded cell phone signal amplifier that delivers twice the uplink power of its competition to reach towers at greater distances than ever before. This multi-amplifier Fusion4Home Max kit gives you better coverage with less signal loss in rural and suburban areas than the other products in it's class.

SureCall Fusion4Home Max Details

The Fusion4Home Max by SureCall is optimized to shine in the weakest of signal environments, making it the most powerful signal booster in its class. For those who live in rural areas where maintaining a connection feels impossible, this should be your go to. It significantly improves voice, text, and data performance for all 4G LTE and 5G cell phones, MiFi hotspots, cellular datahubs, and cellular routers across all North American carriers.

If there is a sliver of cell signal outside your cabin, home, or office, the Fusion4Home Max ensures a consistent connection for streaming, uninterrupted text messages, and crystal-clear voice. No need to worry about cell towers being “too far”, 2XP technology doubles the transmission power to the cell tower for the constant uptime of reliable cell signal and data for your professional or personal needs. For even more reach and power, the antenna can be swapped for one with more gain, such as the Arrow LPDA antenna

Being the first home signal booster to feature SureCall’s Extended Range Technology (ERT), which enables cell signal to be amplified at its strongest point outside, makes this unit a game-changer, especially for those in remote areas. Rather than using a traditional indoor amplifier installed about 30ft from the outdoor antenna, the Fusion4Home Max features an amplifier installed inches from the donor antenna to facilitate ERT and overcome outdoor coaxial cable signal loss. Amplifying the strongest signal possible results in better in-building cell signal quality and wider coverage, more so than with non-ERT competitors.

With the Fusion4Home Max configuration, customers can get up to 6,500 sq ft of coverage under optimal conditions – more than enough for a midsize home or office. Plus, the unit offers up to +72 dB of gain with up to +26 dB in uplink power and the highest downlink power. In fact, when compared to a competitor of the same class, it yielded +7 dB more in downlink, meaning stronger in-building signal and better coverage.

Like other SureCall signal boosters, the Fusion4Home Max allows for frequency band adjustments via the host unit, which helps fine-tune specific carrier bands and avoids overloading the amplifier. While it does boost signal for all carriers at the same time, you can adjust for a preference for a specific carrier.

Installing the SureCall Fusion4Home with Omni/Whip Antennas 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 Omni Antenna, which requires climbing on to the roof of your house and/or up the attic, mounting the Omni Antenna, 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 Outside Antenna: The area with the best signal is where you will mount the Omni 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 Outside Antenna is mounted, connect the included RG-6 cable to the Outside 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 Inside Antenna: Simply attach the Inside antenna to the “Outside Antenna” port of your amplifier. It bends and will attach very easily. 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 Omni Antenna will require rebooting the amplifier. Simply unplug the power supply for 5-10 seconds and replug to reboot the system.

Frequently Asked Questions

Why Should I Buy the Fusion4Home Max?

This booster is ideal for small or midsize homes and offices located anywhere – urban, suburban, and especially remote areas. With its cutting-edge technologies, it’s specially designed to maximize in-building coverage and provide quality cell signal in rural areas, more so than any other booster in its class. If you constantly drop calls, lose service, or experience sluggish data speeds inside your home or office, whether it’s because of building material, cell tower distance, or both, the Fusion4Home Max would be a great investment.

Before you buy, consider maximum coverage. Under perfect conditions, the Fusion4Home Max can cover up to 6,500 sq ft. Coverage will vary depending on the strength of your OUTSIDE signal, so it’s important to understand that while it’s optimized for rural areas, if you only have one bar of service outside, you’ll only get multiple room coverage. For wider coverage, consider a more powerful booster, like the SureCall Fusion Professional or SureCall Fusion5s 2.0 kit.

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

How Do You Install the Outside Antenna and Amplifier?

The SureCall Fusion4Home Max comes with a Yagi antenna.

We recommend placing the Yagi antennas as high as possible on your roof – at least 25 ft above the location you plan to install the indoor antenna. This allows the outdoor antenna to see the cell tower better, as well as reduces oscillation between the two antennas. Aim the Yagi antenna towards your closest cell tower to capture the strongest signal. The antenna should be mounted to a mounting pole or pipe.

Following the antenna, mount the outside amplifier with the included brackets within range of the antenna cable connection. Connect the antenna cable to the amplifier. Make sure all connectors are weatherproofed.

After installing the two outside components, connect one end of the 75ft coaxial cable to the amplifier, run it inside, and connect the other end to the host unit. Then, connect the host unit and the inside panel antenna. Make sure there are at least 25 feet of vertical or 50 feet of horizontal separation from your rooftop antenna. Finally, connect the power supply to the host unit, and switch on the system. You should see a significant improvement in the quality of your signal.

What’s the Difference Between the Fusion4Home, Fusion Install, Fusion4Home Max, Fusion Professional, and Fusion 5S 2.0?

Essentially the difference boils down to power and features.

The Fusion4Home works well in strong signal areas, the Fusion Install is a Fusion4Home unit that comes with free installation and some cable (RG11) upgrades.

The Fusion4Home Max is optimized for weak signal environments and the first to feature an outdoor signal booster, which facilitates ERT (Extended Range Technology) and helps overcome signal loss in the outside coaxial cable for maximum signal boost and wider coverage. It can cover multiple rooms in weak signal areas and up to a whole midsize home or office 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 Fusion4Home Max 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 an elevated area and permission from the building manager or owner to install the outside antenna and amplifier. If you don’t have access to these, we recommend the SureCall EZ 4G window mounted booster kit, which is optimized for apartments.

Do I Need to Contact My Carrier for the SureCall Fusion4Home Max to Work?

Registration with your carrier is required by FCC regulations. You can register your signal booster with your carrier from here.

Can the SureCall Fusion4Home Max Be Expanded with More/Stronger Antennas?

Absolutely! We recommend this to expand your coverage. Should you decide to buy an extra indoor antenna, you will need a splitter and extra lengths of cable 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 high-gain parabolic cellular antenna or "Arrow" LPDA antenna.

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

Second, bear in mind separation between antennas. For your system to work as well as it can, you’ll want around 25 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 25 ft vertically or 50 ft horizontally between both antennas.

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.

What is the Return Policy?

All SureCall units, including the Fusion4Home, can be returned within 30 days. It also comes with a 3 year warranty.
