Poor cell reception is a recurring problem in most of the houses. The main cause of poor cell reception is a weak cell signal. The cell signals coming from the cell tower become weak when they reach our cellular devices due to the distance from the cell tower, bad weather, building materials that reflect the cell signals, etc. That is why it is recommended to use a signal booster in your house to get proper cell reception.

With an in-house signal booster, you will get strong cell signals inside the house all the time. It will help you avoid call drops, slow data speed, and also reduce the noise and distortion during voice calls. Outdoor antenna, amplifier, and indoor antenna are the three major components of the signal booster. Among these components, the outdoor antenna is used for capturing the best outside cell signals.

Two Types Of Outdoor Antennas Of An In-House Cellular Booster

For an in-house signal booster, omnidirectional antenna and unidirectional antenna are the two types of outdoor antenna available. There are several factors that you need to consider while choosing the outdoor antenna for your signal booster.

If you are living in an urban area, you might be surrounded by multiple cell towers. But it doesn’t ensure that you will get a proper cell reception all the time. Urban areas are often densely populated and several high-rising buildings could block the cell signals coming from the cell tower. In these situations, you won’t get a stronger cell signal to make calls or browse the internet.

An omnidirectional antenna is ideal for such situations. This type of outdoor antenna is capable of capturing cell signals from all directions. That means omnidirectional antennas can capture multiple cell signals at a time, which is beneficial for boosting cell signals of different network carriers. The cylindrical shape of the omnidirectional antennas helps them to capture cell signals in a 360-degree angle. This type of outside antenna is also the ideal choice for an in-vehicle signal booster. One other advantage of the omnidirectional antenna is that you do not have to change its position whenever the cell reception is poor.

The other type of outdoor antenna used in in-house signal boosters is the unidirectional antenna. This type of outdoor antenna is usually used in rural areas because the cell reception is often weak there due to the lack of enough cell towers to provide strong cell signals. The nearest cell tower may be miles away and the cell signals that come from that cell tower may not have enough strength to make calls.

The unidirectional antennas are capable of pulling in cell signals from a large distance. Unlike omnidirectional antennas, the unidirectional antennas capture cell signals from only one direction. This will allow the unidirectional antennas to pinpoint one cell tower to pull in the cell signals. One major disadvantage of this type of outdoor antenna is that you may have to often change the antenna position every time you don’t get a proper cell signal.

Yagi antenna and log-periodic antenna are the two types of unidirectional antennas. In most rural areas, yagi antennas are used as the outdoor antenna for the cellular repeater. It is about three times more powerful than an average omnidirectional antenna. However, the log-periodic antenna is often recommended for houses located in very remote locations. Log-periodic antennas can capture cell signals from more than 10 miles and it is about 30 times more powerful than the yagi antenna.

Things To Consider While Choosing The Outdoor Antenna

The first thing you need to consider while choosing the outdoor antenna is the outside signal strength. The type of antenna you need for your in-house signal booster mainly depends on the strength of the outside cell signal. If the cell signal strength is from 0 to -90 dBm, an omnidirectional antenna is an ideal choice. A unidirectional antenna is ideal for cell signals whose strengths come between -91 to -105 dBm range.

If you need to boost cell signals of multiple network carriers at once, you could only use an omnidirectional antenna because a yagi antenna cannot pull signals from multiple cell towers at the same time. Only an omnidirectional antenna is capable of capturing cell signals from multiple cell towers at the same time.

It is always better to use a unidirectional antenna if there is another antenna on the roof and within 30 feet of the signal booster antenna. If you use an omnidirectional antenna, it may capture the signals from the other antenna and affect the functioning of the signal booster system. With the use of a unidirectional antenna, you can eliminate the chance of any possible interference with other antennas.

If you have only a small space to install the signal booster system, the chances of the indoor and outdoor antennas coming close to each other are high and it may affect the signal booster. It is recommended to use a unidirectional antenna to avoid interference and make sure to mount it at least 30 feet away from the indoor antenna.
