Working Diagram (How It Works)
1. The outdoor antenna catches the signal from the tower. 2. Sends outside signal to the booster through a coax cable. 3. The booster amplifies the signal then rebroadcasts the signal indoors to all mobiledevices within range. 4. The system also works in reverse; amplifying outgoing signal back to the tower.The coverage area and the strength of the boosted signal are directly related to two key factors: 1. Signal strength received by the outdoor unit. So, setting up the outsideunit where the signal is the strongest will provide the best results. 2. Distance of separation between the outdoor unit and the indoor unit.Package ContentsThe kit includes the following items: 1. Outdoor Antenna (with mounting kits); 2. Booster(with indoor antenna); 3. Power supply; 4. 60 ft of RG6 cable, for connecting the outdoor antenna and booster;

Signal transmission loss and power level
Coverage area abilityNote: FCC regulations limit the amplification of all cell phone boosters in order to prevent damage to the telecommunications infrastructure. Therefore, the maximum coverage area of a booster depends on the original power level of the signal captured by the outdoor unit.Notice: Not recommended when outdoor signal strength is less than -110dbm(3G/1x) or -120dBm(4G/LTE). The resulting coverage area of the boosted signal will be prohibitively small.

PreparationFind a cell tower nearby! There are a variety of resources available online, here are some third party websites and app recommended. Use these to locate your nearest cell tower, either by street address of GPS coordinates. For U.S. websites: www.antennasearch.com/ www.cellmapper.net/ www.cellreception.com/towers For Canada website: www.cellmapper.net/APP: Tower Locator (iPhone or Android)Find The dBm Reading On Your PhoneHaving an accurate measurement of signal strength in decibels (dBm) is crucial when installing your system. Decibels accurately measure the signal strength you are receiving. Test both 3G and 4G signal for best results by turning the LTE off in the carrier settings of your device.iPhone: need to download third part APP;Android: Settings > About Phone > Status or Network > Signal Strength or Network Type and Strength (exact options/wording depends on phone model).Note: Turn off your cell phone’s WiFi to ensure you are checking the cellular connection. The dBm reading will be refreshed every 30-60 seconds. Want faster results? Once you have a reading, turn on airplane mode. Wait 15 seconds. Turn off airplane mode. The signal strength reading is refreshed.You Will Need (make sure the following things and tools are prepared and ready for your installation. ) · 2~3 hours · 2 people (a person to help with antenna calibration) · Drill (if routing cable through wall) · Recommended: Power Strip with surge protection4
Test InstallationWe STRONGLY recommend doing a test installation before finalizing the installation. Doing a test installation of your cell phone booster ensures that you will get the optimal performance from your system.Step1: Measure the Signal Strength Inside your Home
· Test your current signal strength in multiple locations throughout the home · Record the current signal strength in the table provided for reference

Step2: Select the Location for the Inside Antenna
· Should have access to a power outlet· The indoor unit contains an omni-directional antenna. Choosing a central location in your home will help to maximize your coverage area.

Step3: Select the Location for the Outside Unit1. This is the most critical step and will determine the overall performance of the booster system.2. Using the same method described in Step 1, walk around the outside of your home and test the signal strength. Determine where you have the strongest signal (the dBm reading is closest to zero).3. Generally, the strongest signal will be located on the side of your home facing the nearest cell tower. Keep in mind, the signal strength at ground level may be different from the signal strength at or above the roofline due to obstructions (trees, other buildings, etc.) that block the incoming signal. In most situations, the strongest signal is found about 15 feet above the ground on the side of your home facing the nearest cell tower. Caution· The height of the outside antenna should never exceed the highest point of your home. This is a precaution against damage and safety concerns caused by lightning strikes to the outside unit.· In order to achieve the best performance, try to maximize the distance between the inside and outside antenna.· Ensure that the outside antenna is pointed away from where you plan to install the inside antenna. Self-oscillation may occur if the outside antenna is pointed over the location of the inside antenna.

Step 4: Temporarily Mount the Outside Antenna Use one of the three options to mount the outside antenna on your roof on the side of the house with the strongest signalCaution In order to achieve the best signal coverage effect, there is a certain distance requirement between the indoor and outdoor units. Make sure the inside and outside units are facing away from each other. Minimum Required Separation Distance Between Indoor and Outdoor Antenna 20 ft (6 meters) horizontal distance 13 ft (4 meters) vertical distance(As far as possible) Make sure to meet the Minimum Separation Requirements while at the same time mounting the outside unit in the location with the strongest signal.7
Step5: Connect the System 1. Connect the outside antenna to the 30 feet RG6 cable, fix the connector(In order to avoid internal damage of the antenna connector due to gravity or pulling the cable)Secure the cable near the antenna to prevent cable damage caused by wind shaking2. Connect the “OUTSIDE” port on booster and the outside antenna together by using the coax cable.
3. Connect the inside antenna to the “INSIDE” port on the booster.
4. Plug in the power adaptor and connect it to the nearest power outlet (surge protector recommended).

Step6: Evaluate the Effects
· Now that the booster is up-and-running, re-test the signal strength inside your home at the same locations from Step 1. If the number is higher (dBm reading is closer to zero) than the original reading, your booster is working.· If your signal is not stronger, check the LED lights on the booster and refer to the “Quick Troubleshooting” section at the end of the manual.

Step7: Finalizing Outdoor Antenna Installation Once you have tested the performance of the signal booster and made all necessary adjustments, it’s time to finalize the installation. Outdoor Antenna Installation Make sure that the outside unit is mounted at least 3 feet away from any windows. Option A : Outside Roof Pole Mount (Best Choice) Use an existing pole to mount the outdoor unit in the optimal signal location. Use the picture for reference. Option B : Mounting on Side of Wall (Second Choice)Caution In particular, cables for outdoor antenna locations must be fixed. Otherwise, the internal wires of the cable will be pulled off after the wind has been shaken for a long time. The amplifier will not receive the signal and the system will fail completely.As shown in the figure, it is best to have the cable around a single turn shape and then fix it.Long-term rain or moisture erosion can damage the electrical characteristics of outdoor antenna connectors. Make sure connectors are well screwed in and seal the connectors with glued tape.10
Step8: Finalizing Indoor Installation 1. Choose right position for the indoor antenna · 20 cm away from any other metallic objects · 50 cm away from any windows2. Mount the booster · Choose a ventilated and dry place · Keep away from heat · Don’t cover boosterBooster will about 30 degrees Fahrenheit higher than the ambient temperature, which is a normal phenomenon.Step9: Finalizing and Securing Cable Route
· Find the best route for the cable. Follow the lines of your home to hide the cable in eaves or between the soffit and the exterior wall.· If needed, cable clips can be purchased at most hardware stores.
· Whether the cable is properly
secured is very important for the
entire system. In most cases, the
customer found that the booster
did not work after working for a
period of time because the cable
was not installed securely.
· Carefully arrange the cable along
the outside of the building and
ensure that there are no folds or
kinks. Fix the cable at each corner

Seal and Fix the Connector
Caution
Secure the cable near the antenna to prevent cable damage caused by wind shaking
Properly Handle Excess CablesIf the coiled cable is too close to the antenna or booster, the system will be unstable. Make sure these coiled cables are more than 6 feet(2 meters) from the antenna or booster
Make sure these excess coiled cables are more than 6 feet(2 meters) from the antenna or booster can make your system work more stable.
