Cell signal boosters are now widely used in areas where there is poor cell phone signal strength. These devices have the capability to receive weak signals and amplify them. Hence, they can be of great help to avoid different problems associated with poor cell reception including reduced voice clarity, slow internet, call dropping and more.

A cellular signal booster mainly involves three parts. It includes an external antenna, an amplifier and an internal antenna. The external antenna is used to receive the signals from outside and the amplifier will amplify these signals. These amplified signals will be then retransmitted by the internal area to the required areas. This is how a cell signal booster works.

External antenna is very important for a signal booster, as the performance of the entire device mainly depends on it. The more signals this antenna receives, the higher will be the signal booster’s output. Hence, when installing an external antenna you have to be cautious about certain factors for ensuring its better working. The following is an important factor you have to consider before installing your external antenna. This will help you to maximize its performance.

What Is Antenna Separation?

By antenna separation, we indicate the distance between the external antenna and the internal antenna. There should be enough distance between these two antennas for ensuring that they do not interfere with each other’s working. If there is not enough antenna separation, this will result in reduced performance of your booster. One of the factors that can diminish the performance of a signal booster is oscillation which is often resulted from the close proximity of internal and external antennas. Read along to find out what oscillation is and what its effect is on the performance of the cell signal booster.


When the internal antenna and the external antenna are placed close to each other, they will pick each other’s signals resulting in a feedback loop. This condition is known as oscillation and it can have a great impact on the performance of your booster.

Oscillation can interfere with the reception and the output of signals by both antennas, and if left uncorrected, this problem can damage your cellular network. Hence, it is mandatory to design signal boosters in a way that they can detect oscillation and autocorrect it.

If a signal booster detects oscillation, it will try to reduce its gain or the power to amplify signals. Hence, the strength of the output signal will be low and it will reduce the performance of the booster. If the oscillation is not eliminated even after the reduction of gain, then the booster will shut itself off. Hence, it is important to avoid the problems caused by oscillation.

Make sure that there is enough distance between your external and internal antennas for ensuring that they do not interfere with each other’s performance. This will help you to avoid oscillation and different problems associated with it.
