Cell signal boosters are now becoming greatly popular for their capability to boost the strength of the cell signals inside a building. These devices are becoming a great aid for people who are constantly suffering from different problems caused by poor cell reception. By installing a cellular signal booster in your home, office, or vehicle, you will be able to eliminate a large number of problems like dropped calls, slow internet connectivity, poor voice clarity, etc. Hence, signal boosters are now widely being used in areas with low signal quality.

However, there are certain problems that can greatly affect the performance of your cell signal boosters. They can reduce the gain of your signal booster thereby decreasing the strength of the signals you receive. Therefore, it is important for you to deal with these problems for getting the best performance from your cellular boosters. So you should be aware of these problems for effectively solving them.

The following are some of the common problems that can have a great impact on the performance of your cell phone signal booster.


This problem usually results from the improper installation of interior and exterior antennas of signal boosters. There should be a minimum separation between them so that the signals emitted from your interior antenna will not reach the exterior antenna. If the exterior antenna can receive the boosted signals, then this will result in the creation of a feedback loop. This problem is known as oscillation.

There are FCC regulations regarding oscillation and cell signal boosters. The FCC requires the cell phone signal boosters to automatically detect oscillation and take proper corrective measures. Oscillation might damage the entire cellular network. Therefore, it is important to correct it as soon as possible.

Most signal boosters are designed to detect oscillation so that they can prevent self-damage and the damage of the cellular network. A signal booster will reduce the gain when it first detects oscillation to reduce the strength of the boosted signals. This might be useful for preventing the reception of signals from the interior antenna by the exterior antenna. However, in certain circumstances, this step cannot solve the issue. In such situations, your cellular booster will shut itself off.

If oscillation occurs, it will be indicated by your amplifier with red or orange lights. If you detect this problem, it is important to take corrective measures for improving the performance of the signal boosters.

Increasing the distance between your antennas can help to solve this problem to a great extent. Also, make sure that your directional antenna is pointed away from your home/office. This can also help to solve the issue.

But if the problem is still not solved, then try to bring a barrier between both the antennas. Your chimney or air conditioning units can act as a shield between your interior and exterior antennas.


This problem is usually found in cell signal boosters that are installed in urban areas. This occurs when the strength of the incoming signals are too high so that the amplifier cannot bear it. This problem can also damage your signal boosters. Hence, you have to take corrective measures quickly.

Sometimes pointing your directional antenna away from the offending cell tower can help to solve this problem. However, it won’t be possible in all situations. Hence, you will need another solution to deal with this problem.

If you are also experiencing similar problems, then getting an attenuator can be helpful for you. These are devices that are designed for reducing the strength of the incoming signals. You have to install them between your exterior antenna and the amplifier. An attenuator can decrease the strength of the signals before they reach the amplifier.

Other Issues That Can Affect Your Signal Boosters:

Apart from oscillation and overload, there are certain other factors that can affect the performance of your boosters. It ranges from connection problems to an overheated amplifier. So there are some routine check-ups you have to perform on your signal boosters every 2-6 weeks. Some of them are listed below:

Check The Temperature Of The Amplifier

Sometimes your amplifier can get overheated thereby affecting the performance of the booster. Hence, you have to check the temperature of your amplifier occasionally to make sure that it is working properly.

Check The Connections Of The Amplifier

 Loose connections can also affect your amplifier. So make sure that all the cables connected to the amplifier are properly inserted.

Check If The Cables Are Damaged

Defects of the cables can also cause problems with the performance of the boosters. Hence, it is important to ensure that there are no damaged, pinched, or frayed cables that connect your amplifier to other components of the booster system.

Different problems can affect your signal boosters. Issues like oscillation and overload will be indicated by the amplifier of your booster with red or orange warning lights. But there are many other problems that cannot be easily identified like connection problems, damaged cables, etc. So, perform regular check-ups of your booster to ensure that all the components are working properly.
