This is an antenna type that will be radiating power in either one or even more directions. Because of this capability, this can be generally allowed to maintain the continuous increase of performance to receive and to transmit transmissions. Strength is being focused then power is being transmitted to one direction only in general, thus, the result would be minimized signal loss and optimized signal strength.
Most of these antennas have their ability as well on reducing the interference coming from many sources. Thus, making a directional antenna become the most ideal and popular for use in areas where there are many interference. The interference may usually include some of the transmitting devices such as for weather conditions, some other obstructions, and microwave ovens.
These kinds of antennas are being classified into 2 different types such as the log periodic and the corner reflector. Usually, directional antennas are combined and commonly made available for use as television antennas, specifically designed for in most residential areas. Being used as cellular repeaters is another common purpose. This is used to receive and to transmit signals that are normally out of range for other cellular phones.
Usually, antenna directions are necessary in order for directional antennas to be set up. There are times when there are wrong directions, and the most possible result would be rendering a useless antenna. So it is recommended to check first the areas before starting the process of installation. Through this, the type of antenna to be used can be determined because you already have an idea on potential sources for both obstruction and for interference.
The direction to where the device is pointing is also a factor that needs to be considered importantly. The device can be most effective if it points towards the nearest source for target signal having the least amount of obstructions and interference. And this is one common reason why the mounting process of this device is often a big issue.
Usually, there are some limitations when it comes to the coverage and this is because one general area has been focused only. In larger areas in which a larger coverage is also needed, the device becomes less effective. Thus, for a larger coverage, omni directional types are being recommended for use instead. Omni types have the ability to transmit and receive signal to several directions.
In open areas like the outside grounds of the house or some other outdoor places are the best areas of installation. Closed spaces usually have more obstructions, and thus, limiting the effectiveness of a device. However, before making a purchase of these antennas, be sure that advantages and as well as limitations are considered importantly.
One common advantage of this is for security issues. These devices can help in preventing wormhole attacks. These attacks mean that a packet being forwarded from attackers through higher quality out of band links and the packet is then replayed in other locations. Because of this, all the communications maybe disrupted.
Lastly, one common limitation could be deafness. This usually happens when devices are being used. Network performances will become limited. There are also multiple retransmissions causing the misunderstanding of the nodes between connection since both the route search and mobility are triggered, thus, interactions between upper layers are distracted.
