zBoost TRIO SOHO boosts Verizon 4G LTE and 800/ 1900 Mhz for rest of carriers up to 2,500 square feet. It is ideal for small homes and buildings. Purchase includes omni external antenna CANT-0040, omni internal antenna CANT-0039, and RG-6 cable.

    Setup overview:

    The package includes everything you need: base unit, indoor antenna, power supply, RG-6 coax cable (50 ft.), external antenna and mounting hardware. The omni-directional external antenna receives signals from multiple cell towers.

    Before installing, please note the following important factors in determining your zBoost performance:

      • At least 15 vertical feet is needed between the External Antenna (receives the outside signal) and the Indoor Antenna (rebroadcasts the signal indoors). Separation less than 15 vertical feet will result in decreased performance. 
      • Keep the External Antenna at least 3 feet above any metal.

    FIRST: Mount the External Antenna. Choose a location for the External Antenna using your cell phone to determine the area of strongest signal. 

    The coverage your zBoost provides is largely determined by the quality of signal received by the External Antenna. Choose one of the following options for placement of the External Antenna keeping in mind that if your best signal is one bar, your coverage will be limited to one small room.

    SECOND: Place the zBoost Base Unit where you want to create a Cell Zone.

    Connect the Indoor Antenna to the Base Unit and place it where you need signal. For the widest possible signal area, position the Base Unit near the middle of a room. You may also mount it on an interior wall by first removing the bracket, screwing the bracket to a wall (screws not provided) then snapping the Base Unit back in place keeping the Indoor Antenna vertical. This Base Unit uses an omni-directional antenna that delivers signal in a circular pattern around the antenna.

    The zBoost TRIO SOHO requires at least 15 feet of vertical separation between the Base Unit and the External Antenna. Generally, increasing this distance (up to 40 feet) will increase the performance and decreasing the distance will limit zBoost performance.

    Keep the Base Unit off the floor and at least 2 feet away from other cords, metal objects or other wireless devices such as wireless routers or wireless access points. The zBoost TRIO SOHO performs best when there are no obstructions between the zBoost Base Unit and your mobile device.

    THIRD: Run the provided coaxial cable between the Base Unit and External Antenna.

    Use the provided 50 feet of RG-6 coaxial cable to connect the External Antenna and the Base Unit. To run the cable from exterior to interior through a window, an 8 inch window-entry cable is available for purchase (Part: YX030-08W). Should you need additional cable length, 15 foot extensions (Part: YX030-15W) are available. Please note: Cable longer than 65 feet is not recommended.

    FOURTH: Connect the zBoost Base Unit to the provided power supply and plug into a power outlet.

    When your zBoost system is in place and fully connected, walk throughout your home and verify that you are able to reliably place calls. If the signal strength has improved, your zBoost is working. Remember, coverage varies based on outdoor signal level, building construction, and antenna placement. Coverage in adjoining rooms will be reduced by walls and ceiling/floors.

    Trouble Shooting Tips.

    Upon initial power up, the LED will cycle RED, GREEN and ORANGE for 30 seconds.  After, a series of GREEN flashes will indicate the quality of your setup. Following this, a solid GREEN light indicates normal conditions. If it is not solid GREEN, follow the instructions in the Base Unit LED Indicators section. Adjustments may be needed to optimize performance. If you find the increased signal coverage is acceptable, however, no additional adjustments are needed.

    Should you desire to improve coverage, you may:

    • Relocate the External Antenna in order to capture a better signal –higher is usually better.
    • Increase the distance between the Indoor Antenna and the External Antenna.
    • Purchase an upgrade antenna.

    Questions & Answers


    Ask a Question
    • Solid yellow light after power up. Is there any thing you can suggest that I try to get it to solid green?

      A common cause for solid yellow light is that exterior signal coming in is too strong causing oscillation and automatic shut-down of booster as programmed per FCC regulations. Simply move the exterior Yagi antenna slightly to reduce incoming signal strength and  that should reduce feedback or oscillation due to strong exterior signal strength.

    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. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. 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.

    Kevin K. of Anderson, California gave the following review:

    Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

    Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

    If outside signal is too weak (weaker than -110 dB), 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.

    For non installation-included kits: 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.
