All our boosters are pre-configured and do not require any adjustments on the screen. The only thing you need to focus on is the correct setup, specifically the placement and direction of both the external and internal antennas. Proper antenna positioning is crucial for optimal performance. Please refer to the user guide and detailed instructions to set up the antennas effectively.
If you experience any issues with signal strength or performance, refer to the Troubleshooting steps.
To determine if your booster is working properly, follow these steps:
Check the LED Indicators and/or LCD Screen values.
Ensure the lights are green (for models with LED lights) and check for any warning signs (e.g., a red light or warning message on the LCD screen). Most boosters will display readings or warning symbols if there are issues such as weak input signal, oscillation, or gain attenuation. For information on the booster’s screen readings and LED indicators, consult the user guide.
* If your booster’s LED indicators or LCD screen show steady lights or readings within the normal range (as specified in the user guide), the device is working properly.
Check the Indoor Signal on your phone.
You can use the signal bars on your phone to check the signal strength, but for greater accuracy, we recommend measuring the signal in dBm. You will find the instructions here.
* If the booster is working properly, you should see an improvement in the signal compared to the initial test.
If the signal does not improve, you may need to test the outdoor signal frequency as a troubleshooting step to ensure compatibility with local network frequencies. For further assistance with troubleshooting, please refer to our Troubleshooting steps.
After the booster is installed, you may need to restart your phone or toggle airplane mode on and off to refresh the network and help your phone connect to the stronger, amplified signal. No additional setup is required on your phone; it will automatically connect to the booster’s enhanced signal once it is active.
To ensure optimal performance of your signal booster, follow these guidelines:
Distance Between Antennas (for standard home boosters*)
Please note: The stronger the outdoor signal, the greater the distance should be between the antennas.
Antenna Orientation
To avoid interference and ensure maximum signal amplification, the outdoor and indoor antennas should not be directly aligned with each other. Ideally, place an obstacle (such as a wall, ceiling, or slab) between them. The antennas should face opposite or significantly different directions.
* For vehicle boosters, antenna placement recommendations differ.
You will find detailed instructions on how to properly connect and mount your antennas in our article here. For tips on how to aim and position the antennas correctly, check out our second article here.
Proper external antenna positioning is key to achieve the best performance from your signal booster. The external antenna should be placed in an open area, like a roof top, with minimal obstructions, and oriented toward the nearest base station. Make sure to position it opposite to the indoor antenna to prevent interference.
For a detailed guide on how to position and aim your antennas correctly, please refer to the article.
Mobile networks and TV antennas operate on different frequencies, so interference is unlikely. Installing the booster’s antenna on the same mast as a TV antenna is a common practice, and our customers have not reported issues with this setup. However, for optimal performance, we recommend keeping some vertical or horizontal distance between the antennas.
Assembling a mobile signal booster is typically a quick process and should take no more than 15-20 minutes. Once the system is set up and powered on, you will start seeing improvements in the mobile signal almost immediately.
If the installation is more difficult than expected, there are clear and easy-to-follow instructions to guide you. Firstly, we recommend referring to the user guide of your booster model for detailed steps.
For guidance on connecting and positioning the antennas, you can refer to the following articles:
Additionally, you can watch our video guides on the assembly process on our YouTube channel.
We do not offer installation services, as our focus is on selling equipment and providing after-sales support. However, assembling a booster is simple and does not require specialized knowledge. For detailed instructions, you can refer to the user guide.
The potentially more challenging part might be mounting the external antenna outside your home. This task can easily be handled by any local TV antenna installer. You can ask a nearby TV specialist to install the antenna on your rooftop or TV antenna mast. Additionally, you can check the list of some local installers with experience in cellular antenna installations here: Local Installers List.
For further guidance on how to connect the antennas and position them correctly, please refer to these articles:
If the booster is installed correctly but the signal is still weak or unstable, several factors may be affecting its performance. Learn more.
If your booster is not working as expected, it could be due to a mismatch between the signal type or frequency used by your local network. For a detailed guide on how to ensure compatibility between your booster and network, please refer to our article.
* If you find that the booster is not compatible with your network or the signal type you want to improve, simply submit a request through your customer account, and we'll assist you in finding the correct model and help with the replacement.
Cause: Signal Type mismatch or Frequency mismatch
If the booster readings are good but the bars on your phone haven’t improved, it may be due to a signal type or frequency mismatch.
Solution: For detailed steps on how to resolve this, please refer to our article on ensuring signal and frequency compatibility.
Cause: Poor Indoor Antenna placement
Even with a strong signal from the booster, the placement of the internal antenna or physical obstacles like walls, floors, or large metal objects can block the improved signal from reaching your phone effectively. This can result in weak signal reception even though the booster is working correctly.
Solution:
Cause: Phone is not connecting to the amplified network
In some cases, your phone may not immediately detect the improved signal after the booster has been activated. This can happen due to the phone’s connection process, where it may not quickly recognize the new signal.
Solution:
If you continue to experience issues, feel free to submit a request through your customer account, and we’ll assist you in resolving the problem.
Possible Causes & Solutions:
Even with a stronger signal, heavy network traffic can lead to slower internet speeds.
Solutions:
If the booster is working but the signal doesn’t cover enough distance or drops intermittently, please check the following:
If the external signal is too weak even in the best location, the booster’s output may be limited. In such cases, a more powerful booster may be required.
Indoor Antenna Placement:
Position the internal antenna(s) in an open space, away from obstructions or large metal objects that could block or weaken the signal.
If these adjustments don’t improve performance, reassessing the booster model or adding additional indoor antennas may be necessary. You can request assistance or a model replacement through your customer account.
All boosters are equipped with automatic detection of self-oscillation, which is signaled by an alarm sign on the booster screen “'OSCx”, or red LED lights (for models with LED indicators). For interpreting the signs and values displayed on the screen or LED lights, refer to the user guide of your booster model.
Self-oscillation occurs when the external and internal antennas are too close, creating a feedback loop where the booster amplifies its own signal. This results in automatic gain reduction or even system shutdown to avoid interference.
Solutions:
For further guidance on proper antenna positioning, refer to our detailed guide here.
Following these steps should help eliminate the self-oscillation problem and restore optimal booster performance. However, if the issue persists, try repositioning the antennas further apart or contact support for assistance via your customer account.
Signal boosters are designed to improve mobile network reception for various devices, including routers with a SIM card inserted and other systems such as IP cameras, alarms, etc., that rely on mobile networks. Here’s how to ensure that a booster will work with your mobile device:
Compatibility Check
Ensure that the booster is compatible with the network type your device uses (e.g., 3G, 4G, 5G). Some boosters are specific to certain signal types and frequencies. These are specified in the manual.
To determine which frequencies your device supports, check the device’s specifications. Alternatively, you can test your router’s SIM card by inserting it into your phone and performing the Frequency Test. Instructions are available here.
Connection with routers
The booster can improve the incoming signal for your 4G/5G router. The internal antenna wirelessly transmits the amplified signal to all devices within its coverage zone.
Other Systems
The same applies to other mobile-based devices like IP cameras, alarms, or any other system using mobile signals. These devices will receive the amplified signal from the booster via the wireless connection from the internal antenna, improving their connectivity.
Note: For optimal performance, avoid placing the internal antenna of the booster too close to your router or other devices using the mobile signal. A distance of at least 2 meters is recommended.
After setup, run tests to verify that the signal is properly boosted and that your devices are receiving a stronger signal.
If your area often experiences thunderstorms (such as mountainous regions, coastal areas with dry summer air, or places with monsoon seasons), it's strongly recommended to safeguard your mobile signal booster with a lightning surge protector. Some of our amplifier kits come with a lightning surge protector included. If your kit doesn’t have one, you can buy a compatible surge protector from our accessories page here.
You can consult this article to find more information about installation.
The coverage inside the house and performance of the indoor antennas depend on the outside signal strength. The more you've got outside, the better the coverage inside. It also depends on the construction of your house. If there are many walls and floors, there will inevitably be some signal loss.
In order to improve indoor coverage you can try to adjust the position of the antennas so that they don't face any physical obstacle. If, having done so, the coverage is still insufficient, you can add another indoor antenna, which will be connected to the main unit with a splitter. Check out our accessories page for all the necessary equipment to enhance your signal booster setup.
