Occasionally mobile phone users experience issues from bad signal reception like dropped calls or bad call quality, and this can be very annoying. This happens in areas where cellular signal reception is hindered by factors like geographical barriers, construction materials used in the building, etc. In such situations, a reliable solution for good cellular signal reception is to use a mobile network booster. These devices consist of three units, outside antenna, amplifier, and inside antenna(s). In this article, we will discuss different types of outside antennas, read in to know more.
The outside antenna, also known as the donor antenna, receives a weak signal from the cellular tower and transmits it to the amplifier unit of the mobile network booster. There are two main categories: omnidirectional antenna and a unidirectional antenna. An omnidirectional antenna capture signal from a 360o field, which means it seizes all the signals and is suitable for boosting signals from multiple carriers. Unidirectional or directional antennas seize signals from a 90o field. Therefore, it is more accurate and powerful equipment compared to the former.
Omnidirectional Antennas: The big advantage of using an omnidirectional antenna is that the installation is easier as it can pull signals from a 360o field. However, this causes issues when you are in a suburban or remote area, as it will have difficulty locating the signal from a carrier. Besides, its forward gain is less compared to unidirectional antennas. Therefore, if the outside signal is weak, it might have difficulty in picking out the carrier signal to be amplified.
Yagi Antenna: This is a type of directional antenna and is slightly advanced than the omnidirectional antenna. Also, this is the most common type of unidirectional antenna used in cell service booster. It pulls signal from a field of 45o to 90o in the direction they are pointed. Because of this, it can capture signals from 3 times farther than omnidirectional antennas and gives a higher gain to the signal captured. However, it must point properly in the direction of the cellular tower of the carrier whose signal you want to boost.
Log Periodic Antenna: Of all types of directional antennas, a log-periodic antenna has the highest gain. Apart from capturing weak cellular signals, they are also used for receiving satellite television signals. They are designed to be highly directional with extremely long range. Their field of capture ranges between 5o to 15o, and in some cases, they are 30 times more powerful than a yagi antenna. However, this extremely narrow range also makes their installation quite difficult.
We hope that the details share above will aid in your selection of outside antenna for your cell service booster.
