An Overview About Directional Antenna And Its Advantages
by Richard Richardson
This is one kind of an antenna that will radiate power either in one or in a lot of directions. With this, capability, it will generally be allowed on maintaining to increase the performance to transmit and to receive transmissions. Its strength is also being focused and the power is transmitted in only one direction in general, and thus, resulting to an optimized signal strength and minimized signal loss.
Most antennas also have the ability on reducing the amount of interference from different sources. Thus, the most popular and ideal that can be used in most areas where interference is more is the <a href="http://www.hascall-denke.com">directional antenna</a>. Mostly, an interference would include some common devices used for transmission including some obstructions, microwave ovens, and weather conditions.
The these antennas have two different classifications such as corner reflector and log periodic. Usually, these directional antennas have been combined are mostly available and used commonly as television antennas that are designed specially for the residential areas. These are also used popularly as cellular repeaters in order to transmit and receive signals when there is normal out of range signals for some cellular phones.
Antenna directions are usually important when setting up the directional antennas. At times, having the wrong directions cannot really be avoided, and as a result to this, the rendered antenna would become useless. So the best suggestion would be checking first the areas prior to the installation process. Determining the antenna type through this since you know already on the potential interference and obstruction sources.
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.
And since there is one general area only is focused, there will be some limitations in the coverage. So whenever the device is intended for use in larger coverage, the disadvantage is becoming less effective. Because of this, the omni directional type of an antenna would be more preferred in larger areas. The omni type has the ability to receive and transmit the signals into several directions.
The best suggestions for areas of installation would be outdoors or any other areas that are open like outside the house. Usually, there are more obstructions in closed spaces which can limit the effectiveness. However, the devices may also have some advantages and even limitations which need to be importantly considered before purchase.
One very common advantage is the security issue. With these devices, wormhole attacks can be prevented. The attacks would mean that the packet is being forwarded from the attackers by high quality out of band links then replayed to other locations. For this reason, communication disrupted.
And lastly, a very common limitation is deafness that happened when these devices are used. The network performances become limited. Multiple retransmissions can cause the misunderstanding of nodes between the connection because of the mobility and route search has been triggered, and thus, distracting the interactions between the upper layers.
