Setting Up Your zBoost Signal Booster

❶

 Install the external antenna

Determine the location which provides the strongest signal (typically found on the roof) 

using the signal strength indicator on your cell phone. Once you have determined the 

location of the strongest signal, install the antenna to a mast or pole (not provided). 

During this process, loosely secure the external antenna to the mast to allow the antenna 

to be reoriented for strongest signal. 

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

zBoost performance:

Placing the external antenna in the area of best signal provides the best performance 

and the largest area of improved signal. 

At least 15 feet of vertical separation is required between the indoor antenna and the 

external antenna. Generally, increasing this distance (up to 40 feet) will increase 

zBoost performance.

Avoid placing antenna near metal such as wiring, A/C ducts, truss plates, etc. When 

attaching the cable to the antenna, run the cable straight down from the antenna. 

Antenna aiming

For maximum performance, take special care to point the antenna in the direction of the 

best signal for your wireless service provider. See the user manual for detailed antenna 

aiming instructions or visit www.zBoost.com/install-tips. You may wish to use a YX699 

RF signal meter (available separately). It can identify peak antenna alignment when 

connected directly to the superlog antenna using the provided cable. 

❷

 Install the base unit and indoor antenna

The indoor antenna should be mounted on a wall facing the direction where increased 

coverage is desired. It can be placed directly on a wall using the provided screws and 

wall anchors. A template is provided for correct placement of the hardware. Once in 

place, align the holes on the back of the antenna with the screws in the wall and slide into 

place. 

Keep the indoor antenna off of the floor and at least 3 feet away from other cords, metal 

objects or other wireless devices (The FCC requires that this panel antenna has a 

minimum horizontal separation of 6 feet [2 meters] from other CMRS [commercial mobile 

radio service] devices).

Place the base unit nearby, within reach of a 

power outlet. The base unit can be mounted on a 

wall by first removing the bracket (see ‘Assembly 

Illustration’), screwing the bracket to a wall using 

the provided hardware, then snapping the base 

unit back into the bracket. 

Connect the indoor antenna to the 15 feet of RG-6. 

Next, using the TNC-F Adaptor, connect the 15 

feet of RG-6 to the base unit. 

❸

 Run the coaxial cable between the external 

antenna and the base unit

Connect one end of the cable to the external 

antenna and the remaining end to the base unit. 

Should additional cable length be needed, 15 ft. 

extensions (Part YX030-15w) are available at 

www.zBoost.com. Note: Cable runs longer than 

65 ft. are not recommended unless upgraded to 

RG-11. The maximum recommended length of 

RG-11 is 120 ft.

❹

 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 building 

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. 

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, you may choose to optimize zBoost performance by following the 

instructions in the ‘Base Unit LED Indicators’ section. However, if you find the increased 

signal coverage is acceptable, no adjustments are needed.

1. Unplug the BASE UNIT power supply. 

2. Relocate the EXTERNAL ANTENNA to pick up the 

strongest signal from your wireless carrier. 

3. Move the EXTERNAL ANTENNA as far away from the 

INDOOR ANTENNA as possible, with at least 15 ft. of 

vertical separation (height difference).

4. Plug the BASE UNIT power supply back in.

5. Wait 30 secs. for the BASE UNIT to power cycle on.
