Types Of Exterior Antennas Used In A Signal Booster

Poor cell reception is very irritating because it can lead to call drops, undelivered text messages, slow internet speed, etc. Several factors can cause poor cell reception in an area, such as distance from the cell tower, heavy network traffic, bad weather, obstacles that block the cell signal coming from the cell tower, building materials, etc. The best way to overcome poor cell reception is by using a cell phone extender.

What Is A Cell Phone Extender?

A cell phone extender is an electronic device that is used to boost the cell signal to a usable level in areas where the signal strength is weak. It can be used in your home, office, or vehicle. There are mainly three components in an in-house signal booster; an exterior antenna, an amplifier, and an interior antenna.

The exterior antenna is used for capturing the existing outside signal and sends it to the amplifier. The purpose of the amplifier is to increase the strength of the cell signal to a usable level. The interior antenna will then rebroadcast the boosted cell signal to all the devices in the building.

What Is The Need Of Exterior Antenna?

The purpose of the exterior antenna is to capture the existing cell signal outside the building or the vehicle and transmit the signal to the amplifier. It is one of the three core components of a cellular repeater. A powerful exterior antenna can improve the overall strength of a signal booster kit. There are mainly two types of exterior antennas; omni-directional and uni-directional.

Omni-Directional Antennas

The omni-directional antenna is used to pull in cell signals in a 360-degree pattern that means from all directions. They capture any type of cell signals from multiple cell towers, which is great if you need to boost the mobile signal of multiple carriers at once. These exterior antennas are in the shape of cylinders, just like the radio antenna in a car.

Uni-Directional Antennas

There are mainly two types of uni-directional antennas; yagi antennas and log periodic antennas

Yagi Antenna

It is the most common type of uni-directional antenna, which is used to capture cell signals in a 45 to 90-degree angle in the direction they point.  They are three times more powerful than omni-directional antennas. It is great to boost cell signal if the distance from the cell tower is your main problem.

Log Periodic Antennas

These antennas are about 30 times more powerful than omni-directional antennas and can capture a variety of cell signals, be that 5G, 4G LTE, or 3G. Log periodic antennas can reach cell towers that are about 10 miles away from your location.
