Product Description

Instantly improve cellular signal indoors for all carriers and devices with SureCall's EXTENDED RANGE TECHNOLOGY™ (ERT) designed for large offices, residential MDUs, industrial and enterprise buildings along with educational and business campuses.

5X Max significantly boosts voice, text, and data signals on all 5G and 4G LTE phones and devices delivering enhanced coverage for all North American carriers, including Verizon AT&T, and T-Mobile. The 5X Max wireless solution combines multiple patented technologies to create the most advanced booster delivering the fastest data speeds, largest coverage area, and improved connectivity for all mobile users inside large buildings in the weakest signal areas.

The kit with two internal antennas covers up to 13,000 sq ft and is scalable with additional components that can accommodate up to 12 internal antennas for coverage up to 75,000 sq ft.


  • EXTENDED RANGE TECHNOLOGY (ERT): 5X Max is the first commercial booster to feature SureCall’s proprietary ERT which overcomes signal loss in the outdoor cable by amplifying cell signals at the strongest point outside the building.
  • FULL IOT CLOUD ACCESS: 5X Max includes complete remote monitoring to monitor while off-site. The SureCall Cloud interface indicates signal strength in real-time providing installation feedback and troubleshooting.
  • DUAL INTERIOR PORTS: The indoor booster features two high-power interior antenna ports, which is like having two boosters in one housing. 5X Max is scalable with additional components that can accommodate up to 12 internal antennas for coverage up to 75,000 sq ft.
  • LCD DISPLAY SCREEN: The integrated LCD displays booster status and information that is helpful in setting up and optimizing the booster for best performance. With the system parameters displayed in real-time, the installer is always aware of the current status.
  • POWERFUL TECHNOLOGY: Patented 2XP technology DOUBLES uplink transmission power back to the cell tower ensuring a strong phone-to-tower connection even in weakest signal environments. Exclusive SureIQ automatically optimizes incoming signals, preventing shutdown and ensuring 24/7 uptime with continuous peak performance in both urban and rural areas.
  • BEST-IN-CLASS PERFORMANCE: 5X Max delivers seamless 5G/4G LTE connectivity for all phones and devices on all North American carriers with multiple patented technologies that deliver faster data speeds, maximum coverage area, and improved connectivity inside signal-challenged buildings in the weakest signal areas.

Lightning Surge Protector

We recommend using a lightning surge protector in most cases, but particularly if you'll be installing the kit in an area with frequent lightning. The lightning surge protector should be installed in line with the cable and near the outdoor antenna, and should be properly grounded. The Fusion4Home requires a 75 ohm surge protector.


SureCall warranties all of their amplifiers, antennas, and RF components for 3 years against any workmanship or material defects.

How it works

1 - Outdoor antenna

The outdoor antenna receives and transmits signal to nearby cellphone towers. Outdoor antennas can be either directional or omni-directional.

2 - Cellular amplifier

The amplifier (or "repeater") boosts the signal coming to and from and going to the cell phone tower. The "gain" of the amplifier describes how strong the amplification is - you'll see that word scattered across our product pages.

3 - Indoor antenna

The indoor antenna rebroadcasts the signal inside the building. Some kits have more than one indoor antenna to help distribute the signal.
