 SIGNAL BOOSTER

zBoost DataBlast 4G signal booster extends a 4G Data Zone™ for multiple users/ 

devices operating on the 4G network specified on the front of the box. The zBoost 

DataBlast upgrade system boosts data speeds by up to 20 times when integrated with 

your existing cellular signal boosting system. 

Important

By joining two signal boosters to a single exterior antenna, the 

signal could be reduced by as much as 3dB.

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

• 

At least 15 vertical feet is needed between the Signal Antenna (receives the 

outside signal) and the Base Antenna (rebroadcasts the signal indoors). Separation 
less than 15 vertical feet will result in decreased performance.  
• 

Keep the Signal Antenna at least 3 feet above any metal.

Boost data transmission in 4 easy steps:

FIRST:  Replace existing Signal Antenna with zBoost Quad Band Antenna.

Verify that the location of the Signal Antenna is in the area of strongest signal. The 

coverage your zBoost DataBlast provides is largely determined by the quality of signal 

received by the Signal Antenna. If your best signal is 1 bar, your coverage will be 

limited to one small room.   
To maximize signal coverage, place the Signal Antenna where you find the strongest 

signal (up high or outside) and at least 3 feet above any metal. 

IMPORTANT

: Incorrectly mounting the Signal Antenna to the mounting bracket (see 

figure A) will impede performance. Ensure that the Signal Antenna is properly 

positioned in the mounting bracket as pictured. 

 

To mount antenna to a pole

: Attach bottom of antenna to pole bracket as  

  pictured. Use U-Bolt to secure bracket to pole and fasten.
 

To mount antenna to a flat surface: 

Attach bottom of antenna to pole bracket  

  as pictured. Secure bracket to desired surface using provided screws. Use of 

  the Saddle and U-Bolt are not necessary for this option.

SECOND: Disconnect the coaxial cable from the existing booster Base Unit and 

connect to the zBoost Signal Combiner.   

Existing RG-59 or RG-6 should not exceed 50 feet. If the cable length exceeds 50 feet, 

it should be replaced with RG-11. Existing RG-11 should not exceed 100 feet.
The zBoost DataBlast requires at least 15 feet of vertical separation between the Base 

Unit and the Signal Antenna. Generally, increasing this distance (up to 40 feet) will 

increase the performance and decreasing the distance will limit the performance of 

both boosters.

 

THIRD: Connect one end of the zBoost Signal Combiner to the DataBlast Base 

Unit and connect the remaining end to the existing booster.

  

Assemble the Base Unit and Base Unit Antenna and position the antenna vertically. 

Place the Base Unit next to your existing signal booster. For the widest possible signal 

area, it is recommended that you position the Base Unit near the middle of a room. 

The Base Unit can be placed on a flat surface (e.g., a bookshelf, desk, end table, etc.) 

and performs best when located at least 4 feet above the floor or approximately the 

height of a cell phone when it is typically in use (avoid placing the Base Unit on the 

floor).
Keep the Base Unit at least 2 feet away from other cords, metal objects or other 

wireless devices such as wireless routers or wireless access points. The zBoost 

DataBlast performs best when there are no obstructions between the zBoost Base 

Unit and your mobile device.

Important:

 The cable connections should remain hand-tight. Once you have them in 

their permanent location, verify that all three connections remain secure. 

Note: 

To mount it on an interior wall, first remove the silver bracket from the Base Unit, 

mount the bracket to a wall with 2 screws (not provided), then placing the Base Unit 

back into the bracket keeping the antenna vertical.

FOURTH: Connect the DataBlast 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 

or office and verify that you have fast, reliable data speeds. 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 building materials. 
Upon initial power up, a solid GREEN LED should appear indicating normal conditions. 

If a RED light appears, adjustments may be needed to optimize performance. If you 

find the increased signal coverage is acceptable, however, no additional adjustments 

are needed. See LED Indicator section for more information.

Should you desire to improve coverage, you may:

•  Relocate the Signal Antenna in order to capture a better signal–higher is better.

•  Increase the distance between the Base Units and the Signal Antenna.

• ALTE-AWS
