Product Description

SureCall Fusion2Go Max is the most powerful in-vehicle cell phone signal booster available on the market. It boosts 2G, 3G, 4G LTE, 5G E cell signals for all cellular devices and carriers in the US, Canada, and Mexico for best performance in both urban and rural environments.

SureCall Max uses Extended Range Technology™ (ERT) to capture cell signals at their strongest point outside the vehicle, improving call reliability and data performance inside the vehicle. It also features the strongest transmit signals back to the cell towers to keep you connected in the weakest signal environments.

We think of SureCall Max Fusion2Go kit as a "Fusion2Go 3.0" with double the power on the low bands, which are the main frequencies used in rural areas where the majority of mobile boosters are used. It is equipped with Extended Range Technology (ERT) that will help maintain connectivity even further off the grid, while improving Signal to Noise Ratio (SNR) which provides a higher quality signal that translates to better data performance.

Please note limitations and reason for those limitations.

Limitation: If you plan to purchase another set of exterior and interior antennas to move the base unit from one vehicle to another easily, that is not possible with this kit. Exterior antenna cannot be detached from signal amplifier base unit. Therefore, the main base cannot be moved over to another vehicle without removing exterior antenna with its cable.

The reason for this limitation is due to its extended range technology (ERT) which makes this the most powerful multi-carrier vehicle cell signal booster that it is. With this technology, its exterior antenna acts as a pre-booster. Thus, its exterior antenna boosts signal after catching it to pump maximum signal inside vehicle for the main booster to amplify (again!). ERT helps enable this kit to provide higher uplink and downlink power than any other multi-carrier cell phone booster. Therefore, to ensure that this exterior antenna with built-in prebooster is not replaced inadvertently or by mistake with another basic antenna making this kit useless, its exterior antenna cable has been permanently attached to the base.

If you need a vehicle cell signal booster kit that can be transferred from one vehicle to another quickly without removing its exterior antenna & cable, then please consider SureCall Fusion2Go 3.0 or SureCall Fusion2Go 3.0 RV cell phone booster kit (Non-ERT). Fusion2Go 3.0 and Fusion2Go 3.0 RV kits offer slightly lower uplink & downlink power but they are such that you can buy an extra set of their antennas for installation in another vehicle so that you can unscrew both antenna cable connectors from base unit to switch the main booster unit easily from one vehicle to another without having to remove and re-route their antennas and cables.

Most Powerful Vehicle Cell Phone Signal Booster for All Carriers.

  • Unique Feature # 1: SureCall's game-changing patented Extended Range Technology (ERT) and 2XP technologies that provides twice the uplink power, increased downlink gain, and higher Signal to Noise Ratio (SINR) than the closest competitor.
  • Unique Feature # 2: Stay connected in the weakest of signal environments and enjoy fastest data speeds, better call clarity, largest in-vehicle coverage and more simultaneous users over all other competing boosters.

What is unique about this kit?

Unique benefits of SureCall Max Signal Booster

With ERT technology, the signal is boosted in exterior antenna and boosted again in signal amplifier. With ERT, exterior antenna captures cell signals at their strongest point outside the vehicle, improving signal quality to help maintain calls and better data performance inside the vehicle. Extended Range Technology (ERT) adds 2X the power over ALL OTHER wide band vehicle signal boosters to help stay connected where others simply cannot. It offers the strongest uplink signal resulting in maximum vehicle-to-tower connection even in the weakest of signal areas.

Only 4 Steps to SureCall Fusion2Go Max Vehicle Cell Booster Set-Up:

SureCall Fusion2Go Max Vehicle Cell Phone Signal Booster Set-Up Diagram


Place the magnetic-mount antenna on the top of your vehicle, preferably toward the back, Ensure that the antenna has at least a 12-inch radius clear of obstructions and other radiating elements, such as a radio antenna. *For non-magnetic vehicle body, use the adhesive option included in package. Run the cable from the outside antenna across the car’s roof and into the car. To hide and protect the antenna cable, carefully pull down the door seal, run cable underneath it and push the seal back into place. Note: The outside antenna must not be collocated or operating with any other antenna or booster.


Identify a location for the inside antenna on or near your front dashboard that is: (1) Within 2-3 feet of typical cell phone location, (2) At least 8 inches (20cm) from cellular devices and (3) At least 4 inches (10cm) from metal. Peel Velcro backing and apply to a clean dry surface in your chosen location. Or try this - Use the free vent clip provided with your product as a mounting surface then simply clip to an air vent.


Select a well-ventilated location for the booster that is away from excessive heat, direct sunlight, and moisture. We often suggest installing beneath a seat or within the front console. Connect the cable from the outside antenna to the connection marked OUTSIDE and connect the cable from inside patch antenna to the connection marked INSIDE. Hand tighten the connections and secure any loose cable.


Connect the DC power cord connector to the signal booster and the adapter end to the cigarette lighter adapter to your vehicle. Once all connections are connected, turn the power switch on the adapter to ON. The Power LED will illuminate to indicate that the signal booster is ready for use. Note: When your car is off, turn the power switch to OFF to keep the booster from continuing to draw power to your vehicle. Place a call in a location you have previously experienced poor signal and confirm that your phone is receiving a boosted signal. Normal operation is indicated by Green LEDs (both flashing and solid). In the event Red LEDs appear, antenna adjustments may be needed.

What is the difference between different styles available?

While the exterior antenna cable that runs from outside ERT antenna to signal amplifier main unit is a RG-174 10 feet long coax cable, the length of coaxial cable that runs from signal booster base unit to inside antenna varies with each kit. The Patch Antenna Kit includes RG-174 10 ft. inside cable from amplifier to inside antenna (same length as exterior antenna cable length). However, the Whip on-amplifier antenna kit, table-top antenna kit, and wall-mount panel antenna kit includes low loss RG-240 20 ft. cable which is needed for longer runs in bigger vehicles such as RVs and Motorhomes. More importantly, the Gain provided by respective style/type of interior antennae within each kit varies as follows:

  • Patch Antenna Gain (recommended for car, truck, SUV):
    LTE-A (AT&T) = 1.1 dBi. LTE-V (Verizon) = 1.1 dBi. 800 MHz = 1.1 dBi. 1900 MHz = 3 dBi. 1700 MHz = 3 dBi. 2100 MHz = 3 dBi.
  • Amplifier-Mounted Whip Antenna Gain (recommended for Small Size RV, Motorhome):
    LTE-A (AT&T) = 1.2 dBi. LTE-V (Verizon) = 1.2 dBi. 800 MHz = 1.2 dBi. 1900 MHz = 3 dBi. 1700 MHz = 3 dBi. 2100 MHz = 3 dBi.
  • Tabletop Antenna Gain (recommended for Medium Size RV, Motorhome):
    LTE-A (AT&T) = 2.5 dBi. LTE-V (Verizon) = 2.5 dBi. 800 MHz = 3 dBi. 1900 MHz = 5 dBi. 1700 MHz = 4 dBi. 2100 MHz = 5 dBi.
  • Wall Mounted Panel Antenna Gain (recommended for Large Size RV, Motorhome):
    LTE-A (AT&T) = 7 dBi. LTE-V (Verizon) = 7 dBi. 800 MHz = 7 dBi. 1900 MHz = 10 dBi. 1700 MHz = 10 dBi. 2100 MHz = 10 dBi.

Optional Cable Lengths.

Integrated cable from exterior antenna to signal booster base unit will not vary from ten feet cable provided. Interior antenna cable length of 20 ft. is provided with all Marine / RV kits (not the Patch Antenna Kit for car/ truck/ SUV that includes the shorter 10 feet cable which is enough for most cars, trucks and SUVs). However, internal antenna cable lengths can vary with purchase of any of the following cables. Please note that shorter the cable length you use, the better - because shorter lengths incur less Gain loss. If you plan to buy a cable for extending your existing cable length instead of replacing it, know that you will need the connector SC-CN-11 to connect it to your existing cable. The following cables are low loss, weatherproof, heat-shrunk and tested to perform at their best.

  • 10 feet SC-240 Cable with FME-Female/N-Male connectors (SC-004-10-FN).
  • 20 feet SC-240 Cable with FME-Female/N-Male connectors (SC-004-20-FN).
  • 40 feet SC-240 Cable with FME-Female/N-Male connectors (SC-004-40-FN).

Questions & Answers


Ask a Question
  • From how far away cell towers can this catch signals?

    It can do so, from up to 50 miles away - for all carriers.

  • I ordered the item: 20' SureCall 240 Cable w/N-Male & FME-Female connectors (White) because on the product description it was listed as a compatible extension cable. Unfortunately, N-Male connector does not work with the FME-Female connector that is on the end of the Fusion2Go Max antenna wire. How do I connect it to extend the cable length?

    That cable would have worked if you were connecting its other end to an antenna that has N connectors. You can use an adapter like the SC-CN-11 if you want to use the existing cable without doing anything else. Just know that adding additional lengths of cable to existing cables will add more signal degradation.

  • I am a Sprint customer (Sprint SIM usually on band 41 2500MHz) and would like a vehicle signal booster that works on the new Sprint-Tmobile. Can you assist?

    Our boosters will support bands 2, 4, 5, 12, 13, and 25, but not band 41. T-Mobile uses bands 2, 4, and 12. This Fusion2Go Max is one suggestion that will enhance the supported bands mentioned.

  • Can you permanently mount this without the cable showing and coming through the door?

    Unfortunately, the Fusion2go Max Fin antenna is proprietary to the booster itself.

    Its cable is attached to signal amplifier on other end.

    Therefore, this kit cannot be used with the NMO drill-in type antenna.

    If you want to have it professionally installed, you can buy a similar kit, the SureCall Fusion2Go 3.0 Fleet where there will be no wire showing nor going thru the door.

  • I have a jeep wrangler with a soft top. Would this be able to work for me, and how?

    The Fusion2go Max will work as long as you can mount its outside antenna on the top far away from inside antenna. Basically an antenna one on each end. There is an exterior antennas adhesive option included in the package for non-ferrous soft-tops.

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Please check outside signal level in decibels before ordering. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

If it is too weak, submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

Please note: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
