zBoost CONNECT boosts voice and text for your personal workspace

Setup overview:

The package includes everything you need: amplifier base unit, power supply, indoor antenna, 50 ft. of RG-6 cable, window-mount signal antenna and suction cup attachment hardware. The wide radio wave beam width directional antenna receives signals from multiple cell towers.


Check For Signal Strength

Before placing a zBoost in your home, make sure that you can place calls near the window or wherever you plan to place the Signal Antenna. zBoost can only bring signal into your home when signal reaches the Signal Antenna.

Using your cell phone, place a call near this location to confirm that enough signal is present to complete the call.

If you can reliably make and receive calls at that location then zBoost can bring the signal into your home.


Setting Up Your zBoost Signal Booster

FIRST: Place the Signal Antenna on the interior of a window located in the area of best signal.
Determine the location that provides the strongest signal using the signal strength indicator on your cell phone. Find the location on the window that provides the most bars of signal strength. Fasten the suction cup attachments to the Signal Antenna and secure to your window.

In order to capture the strongest signal, do the following:

  1. Move the antenna around the window – higher is usually better.
  2. Use the long suction cup attachments provided, in order to create a greater angle in which to capture the signal. The suction cups must be vertical on the window.
  3. For best performance keep the Signal Antenna 2 feet from any metal.

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, it is recommended that you position the Base Unit near the middle of a room or mount it on an interior wall. This Base Unit uses an omni-directional antenna that delivers signal in a circular pattern around the antenna. This product does not require vertical separation; however, the Signal Antenna and Indoor Antenna should have at least 8 feet of horizontal separation. Increasing separation of the 2 antennas will optimize zBoost performance.

The Base Unit can be mounted either directly on a wall or placed on a flat surface (e.g. a bookshelf, desk, end table, etc.). For best results, 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. zBoost 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 Signal Antenna.
Use the provided RG-6 coaxial cable to connect the Signal Antenna and the Base Unit. Coaxial connections can loosen when the cable is moved. Be sure the connections stay hand-tight.

FOURTH: Connect the zBoost Base Unit to the provided power supply and plug into a power outlet
NOTE: The Base Unit can be plugged into a standard 2 or 3 prong 110 VAC receptacle using the Included power supply. The power supply consumes less than 10W (less than 0.2A AC).
Upon initial power up, the LED will cycle RED, GREEN and ORANGE for 30 seconds. After 30 seconds, 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 of the user manual. Adjustments may be needed to optimize performance. If you find the increased signal coverage is acceptable, however, no additional adjustments are needed.

Improving Your Coverage Area

Remember, coverage varies based on outdoor signal level, building construction, and antenna placement. Coverage in adjoining rooms will be reduced by walls and building materials.

Should you desire to improve coverage, you may:

  • Relocate the Signal Antenna to capture a better signal. Some newer windows use material that blocks signal. In this case, the Signal Antenna would need to be mounted outside of the window.
  • Increase the distance between the Indoor Antenna and the Signal Antenna.
  • Purchase an upgrade Indoor Antenna
