Preparation

You Will Need (tools not included)
Make sure the following materials are prepared and ready for your installation.

1 to 2 hours
2 people (a person to help with antenna calibration)

• Ladder
• Drill (if routing cable through wall)
• 1”-3” diameter existing pole for mounting Outdoor Antenna (Pole Mount can be purchased separately if needed)
• Recommended: Power Strip with surge protection

NOTE: These instructions will walk you through a “soft” install process to find the optimal locations for the inside and outside antennas, then through the permanent installation process.

Step 1: Inside Antenna Placement

Place the Inside Antenna where you need the greatest signal boost and place Booster in your desired location.
NOTE: Do not connect the booster to power until the system is fully installed. Choose a proper position for the indoor antenna

• 1 feet away from any other metallic objects
• 3 feet away from any windows

(STEP 1 cont.)
Booster Placement

Mount the booster

• Choose a ventilated and dry place
• Keep away from heat
• Don’t cover booster

**** Booster will be about 30 degrees Fahrenheit higher than the ambient temperature, which is a normal phenomenon.

Step 2: Mount & Point Outside Antenna Toward Nearest Cell Tower

Pole mounting and wall mounting options are included. The pole mounting option is preferred because it will be easier to adjust to the direction of the cell tower.
Attach the Mount to the Outside Antenna and use the Bracket Clamps to attach the Antenna to a pole or exhaust pipe.

Make sure that the outside unit is mounted at least 3 feet away from any windows.
An outdoor antenna must be installed over the roof line.
NOTE: Mounting on the existing roof exhaust pipe would be a good time- saver option. Watch out for power lines.
Point the Outside Antenna toward the nearest cell phone tower. To find the nearest tower, use an app such as ‘Open Signal’. This is the most critical step of the installation process because it will determine the overall performance of the booster system.

Keep enough distance between outside and inside antenna

NOTE:
The Outside Antenna must be at least 40 feet (12 meters) Straight line distance or 30 feet (9 meters) horizontal 20 feet (6 meters) vertical from the Inside Antenna for best performance.
The greater the separation between the Inside and Outside Antennas, the better performance you will get from the booster.
Select the optimal mounting location for the outside antenna

After identifying the area of the strongest signal, choose the surface where you will mount your outside antenna.

1. The location should allow for sufficient separation between the outside antenna and inside antenna.
2. In order to better receive external signals, the outside antenna is best installed in a higher position on the house, but please pay attention to lightning protection.

Antenna mutual position

The outside antenna should be oriented in a way that it does not “face” the inside antenna.

Caution: Do not aim an outside antenna towards inside antenna.

Caution: The inside antenna cannot face the outside antenna.

Step 3: Route & Connect Outside Antenna To Booster

Connect the white 3D-FB Cable to the Outside Antenna and route cable into the home, secure the cable near the antenna. All connections should be finger- tightened only.

Route cable to the Booster and connect to the port labeled ‘OUTSIDE’.

Step 3: Route & Connect Inside Antenna To Booster

Connect the Inside Antenna to the ‘INSIDE’ port on the booster.

(STEP 3‐A cont.)
Wall Mounting Option 

Step 4: Power Up The Booster & Optimize The System

Plug in the Power Supply and connect it to the nearest power outlet.
NOTE: We strongly recommend using a power strip with surge protection.

Measuring Booster Performance

How To Get Signal Strength As A Number

iPhone®

Dial 3001#12345# then press Call.

1. Hold down power button until you see ‘Slide to
   Power Off’.

2. Then release the power button.

3. Hold the Home button until your main screen appears.

If you want to check 3G/1x but your iPhone is picking up a 4G/LTE signal, go to Settings>Cellular>Cellular Data
Options>En_x0002_able .LTE>Select Off.
After you system is set up, you can go back to the dots signal by once again dialing 3001#12345# and then pressing call. When the menu comes back up, tap “phone” in the top left corner of your phone.

iPhone®
iOS 11 – current
iOS 11 and later no longer displays the decibel (dBm) reading in ‘Field Test Mode’. Tip: Using the dot signal strength indicator on your cell phone can assist you in finding the strongest signal direction as well as placing calls in different locations.

How To Confirm That Your Installation Is Correct And Effective?

Having an accurate measurement of signal strength in decibels (dBm) is crucial when installing your system. Decibels accurately measure the signal strength you are receiving.

(MEASURING BOOSTER PERFORMANCE AFTER INSTALLATION cont.)

Signal strength at 6 feet from the indoor antenna

Note here: dBm
Signal strength at 6 feet from the outdoor antenna
Note here: dBm

Compare Results

If the signal strength in decibels (dBm)at 6 feet from the indoor antenna is 15‐20dB higher than the signal strength at 6 feet from the outdoor antenna, then your system has achieved the optimum results.
Note: Since it is a negative number, the smaller the number, the greater the signal strength.
DID YOU KNOW a signal increase of just 3dB is 2 times the power and signal amplification?

Light Patterns

Band Indicator Lights Solid Green:

• Every time the power is powered on, all the band indicators will turn orange for about 1 second. This indicates your booster has passed the self-test and is in good condition. When the booster is functioning properly, all the band indicators will remain solid green during operation.

DC Power Indicator Correct Functioning:

• Power Light should be solid green after powered on.

Band Indicator Lights Blinking Red:

• Band has reduced gain. Which lights blinking indicate that the corresponding bands have reduced power due to a feedback loop condition called oscillation. This is a built-in safety feature to prevent harmful interference with a nearby cell tower. If you are already experiencing the desired signal boost, then no further adjustments are necessary. If you are not experiencing the desired boost in coverage then refer to the Troubleshooting section.

Band Indicator Lights Solid Red:

• Band has shut off. This is due to a feedback loop condition called oscillation. This is a built-in safety feature that causes a band to shut off to prevent harmful interference with a nearby cell tower. Refer to the Troubleshooting section.

DC Power Indicator Off:

• Please check your outlet, make sure it is normal.

Troubleshooting

IF YOU ARE HAPPY WITH THE COVERAGE, THESE LIGHT ISSUES DON’T HAVE TO BE RESOLVED. YOUR CARRIER’S BAND HAS NOT BEEN AFFECTED.
FIXING ANY BAND INDICATOR LIGHTS BLINKING RED ISSUES

Band Indicator Lights Blinking Red

1. Band Indicator Lights Blink 1 To 15 Times ( 1 cycle) Then Turn Green That means the gain lowered 1~15 dB. If your coverage is good and reception is good, you can ignore the blink; If you would like greater coverage and better reception, please increase the distance between the outside antenna and
   inside antenna to improve the gain.

2. Band Indicator Lights Blink All The Time
   That means the gain lowered 16~25 dB. Please increase the distance (horizontally or vertically) between the outside and inside antenna to solve the oscillation problem. Check and install the whole system again.

FIXING ANY BAND INDICATOR LIGHTS SOLID RED ISSUES

Band Indicator Lights Solid Red
That means to shut down. Please increase the distance (horizontally or vertically) between the outside and inside antenna to solve the oscillation problem. Unplug and re-plug in the power supply. Check and install the whole system again.

How to solve the problem of oscillation:

1. Keep enough distance between the inside and outside antenna, Minimum Required Separation Distance Between Inside and Outside Antenna: Straight line distance over 40 feet(12 meters) or 30 feet (9 meters) horizontal distance 20 feet (6 meters) vertical distance (as far as possible).
2. Verify outside and inside antennae face away from each other.
3. You may need to undo and redo the connection completely. Unplug and replug in the power supply.

FIXING ANY BAND INDICATOR LIGHTS SOLID ORANGE ISSUES

Band Indicator lights Solid Orange
That means the corresponding band has shut off due to interference from other band signals.
Outside antenna needs to be adjusted.
Pole Mount Option: Rotate the outside antenna away from the strongest cellular signal in small increments(45°). Then power it on again to see if the band indicator light is solid green.
Mounting on side of the roof option: Change mount location or increase the distance between the outside and inside antenna. Move the outside antenna to the location of the home/building. Then power it on again to see if the band indicator light is solid green. Then secure in place.

FIXING DC POWER INDICATOR OFF ISSUES
Please verify your power supply has power; Please verify the power cord is tightened; Contact with us by email or call for a replacement.
