Cellular signal booster is a device that helps in improving the signal reception of an area. If you are living in a place where the mobile signal is weak, you can use a signal booster to amplify or to strengthen the receiving signals. There are three components in a signal booster, the outside antenna, the amplifier and the inside antenna. It is necessary for signal booster system to have the most appropriate outside antenna because this part is responsible for intercepting the signal from the surroundings. There are mainly two types of outside antenna. Even though both of them are made to execute the same function, there are some differences between these models such as follows.
Directional Antenna Or Yagi Antenna
This is one of the most commonly used signal booster antenna in remote places or in places where the distance to the mobile tower is very long. This antenna uses a reception pattern similar to that of flashlight, that is, this antenna is capable of intercepting signals from a single direction. It is more suited in homes and buildings where there are not many interruptions between the mobile tower. Most of the yagi antennas are capable of procuring signals of a single carrier. Since its signal reception is focused on to a single direction, it gives better coverage than other types of antenna.
Omni Directional Outside Antenna
It is a cylinder shaped outside antenna used in a mobile signal booster system. Unlike yagi antennas, this type of antenna is capable of intercepting signals from a 360 degree radius. Due to the wide coverage, it cannot procure signals from long distance mobile towers. However, it is ideal for buildings and houses where the signal interception is weak due to heavy traffic on the broadcasted signals. This type of antenna is also capable of intercepting signals of multiple carriers. It is always better to keep this antenna at the maximum height and where the outside interruptions are low.
The above mentioned are two common types of outside antennas used in cellular signal boosters. For a signal booster to amplify and broadcast signals with high strength, it is necessary to fix the perfect outside antenna that is suitable for your location. If you are residing in a remote area, it would be better to buy a yagi antenna and if you are experiencing weak signals in a city, the Omni directional antenna will be the best choice.
