A proper cell signal is necessary for making a call or browsing the internet. But most often you won’t get proper cell reception at your home, office, or car; which is really frustrating. The only option you have to avoid call drops is by installing a cellular repeater or a signal booster, which consists of an outside antenna, an amplifier, and an inside antenna.
What Is The Need Of An Outside Antenna?
An outside antenna is one of the most important components of a cell phone booster system. A signal booster system works by increasing the strength of the cell signal to a usable level. For that, the amplifier unit of the signal booster needs a cell signal. It is the purpose of an outside antenna to capture the existing outside cell signal and send it to the amplifier unit via coaxial cable. A correctly positioned powerful outside antenna will dramatically improve the performance of your signal booster system.
Types Of Outside Antenna
Outside antennas are mainly divided into two categories; omni-directional antenna and uni-directional antenna. The hardest part of choosing a signal booster for your house is identifying which type of antenna is necessary for your situation.
An omni-directional antenna is the most common type of outside antenna used for the houses surrounded by multiple cell towers. This type of outside antenna is able to collect cell signals in a 360 degree pattern. They can capture cell signals of multiple carriers at once. The main disadvantage of the omni-directional antenna is that it does not give much gain to the incoming cell signal. The shape of the omni-directional antenna is like a cylinder, like the radio antennas in a vehicle.
Uni-directional antennas are of two types; yagi antennas and log periodic antennas.
Yagi Antennas are the most common type of uni-directional antenna used in a cellular antenna. This type of antenna is used to collect cell signal from a single direction; more specifically in a 45 to 90-degree angle. Yagi antennas are three times more powerful than omni-direction antennas. Yagi antenna is very effective in boosting 5G, 4G LTE, and 3G signals if the distance from the cell tower id the main reason for poor cell reception.
Log Periodic Antennas are thirty times more powerful than yagi antennas. They can pull in all types of call signals, including 5G, 4G LTE, 3G, and Wi-Fi. Log periodic antennas are the best choice for capturing cell signals in remote areas. This type of antenna can pull in cell signals coming from cell towers that are located up to 10 miles away. One major drawback of log periodic antenna is that it can hit only one cell tower at once.
Which Type Of Antenna Is The Best?
We can compare the two types of outside antenna to a lantern and a torch. The omni-directional antenna is a lantern, which shines the light in all directions. The uni-directional antenna is like a flashlight, which focuses the light beam in one direction.
A log periodic antenna can be compared to a laser-pointer. It may not light up much of the area, but it can reach really far away. If you are surrounded by many cell towers and still getting a proper cell reception due to the obstacles that block the cell signal, you can try the omni-directional antenna.
A yagi antenna is the best option if you are living far from the nearest cell tower but not too far. You will probably need a log periodic antenna if you are living so far off the grid because you need the most powerful antenna available to capture the cell signal.
Best Place To Install The Outside Antenna
The best place to install the outside antenna of an in-house signal booster is the rooftop because it might be the highest point in your house and there will be minimum obstacles to block the cell signals coming from the cell tower. When you mount the outside antenna, make sure that it is away from other antennas of your house because they will interfere with the cell signals.
You can mount the outside antenna in a corner of your house that receives the best outside signal if the rooftop is not an option for mounting the antenna. 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.
In order to install the outside antenna, you have to find the area of your house where the signal reception is the strongest. 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. Make sure not to mount the outside antenna near other electronic devices.
