If you are experiencing poor cell reception at your home, the best way to overcome it is by installing a signal booster, a device that can increase the strength of the cell signal. A signal booster has three main components. They are external antenna, amplifier, and internal antenna.
The purpose of the external antenna is to capture the existing outside cell signal. The performance of the signal booster depends on the cell signal that is captured by the external antenna.
Types Of External Antennas
Omnidirectional antenna and unidirectional antenna are the two types of external antennas used in a cell phone booster system. Choosing the type of antenna for your house is based on several factors such as the availability of cell signal, distance from the cell tower, the number of network carriers, etc.
This is the most common type of external antenna used for capturing the cell signal if your house is surrounded by multiple cell towers but you are not getting proper cell signals due to the obstacles that block the cell signals. Omnidirectional antennas are capable of capturing the cell signals from all directions.
If you need to collect cell signals from multiple network carriers at once, then an omnidirectional antenna is your best choice. One disadvantage of the omnidirectional antenna is that it does have much range for collection signals from a long distance. Omnidirectional antennas usually come in a cylindrical shape.
There are two types of unidirectional antennas; yagi antennas and log periodic antennas. The most common type of unidirectional antennas used in a cellular repeater is the yagi antenna. It is more powerful than an omnidirectional antenna.
Yagi antennas are used to collect cell signals from a single direction. Yagi antenna is very effective in boosting cell signals if the distance from the cell tower is the main reason for poor cell reception. It is the ideal choice to boost 5G, 4G LTE, and 3G signals.
Log periodic antennas are more effective than yagi antennas in capturing cell signals coming from distances of more than 10 miles. It is thirty times more powerful than yagi antennas. If you are living in a remote area where the nearest cell tower is far away, a log-periodic antenna will be the ideal choice for the signal booster.
Best Location For External Antenna
The rooftop is the best place to mount the external antenna of an in-house signal booster because it might be the highest point in your house and the obstacles that block the cell signals coming from the cell tower will be less. When you mount the external antenna, make sure that it is away from other antennas of your house because they will interfere with the cell signals.
If the rooftop is not an option for mounting the external antenna, mount the antenna in a corner of your house that receives the best outside signal. When you install the outside antenna, do not install it near the amplifier unit or the inside antenna. You should keep at least a 15 feet vertical separation between the amplifier unit and the outside antenna.
You have to find the area of your house where the signal reception is the strongest for installing the outside antenna. Walk around the perimeter of your house with a cell phone and look at the signal bar to find the area of the house with better signal reception. There are also specific mobile applications that can help you find the best outside cell signal.
Antenna separation simply means the distance between the external and internal antennas. A safe distance is essential to ensure that both external and internal antennas do not interfere with each other. Therefore, make sure to leave a significant distance between the external antenna and internal antenna during the installation of the signal booster.
The performance of the cell phone repeater will be negatively affected if there is no significant distance between the external and internal antennas. Without enough antenna separation, oscillation can occur which diminishes the performance of the cell phone booster.
If you mount the external and internal antenna close to each other, both the antennas will start to pick up each other’s signal and creates a feedback loop. This will cause a significant reduction in the performance of your cell phone booster. The oscillation will interfere with the reception of the cell signal and also with the output signal. If the interference continues, it will eventually damage the cellular network and your cell reception will compromise.
When oscillation is detected, the cell phone booster will reduce the gain or reduce the power for boosting the cell signals. Due to this, the resulting cell signal will not have enough strength and the performance of the cell phone booster will be affected. The best way to avoid that is by ensuring a significant distance between both external and internal antennas.
