What Is Parabolic Wifi Antenna ?

When we talk of wifi antenna, one thing that comes to our mind immediately is a parabolic microwave antenna. This is the basic model of an antenna and it was initially used for military purposes during World War II. this type has a higher power transmission and therefore is better suited for lower bandwidth usage.


Usually these antennas use a tri-band figure and consist of the low, medium and high bandwidths. Most of these antennas would have a center element with a single line tuned between five and eight megahertz. The flat base is supported by the tri-band figure and in some cases the single line element is supported by a coaxial cable. Some devices can even support ISM (Integrated Services Maintained Model) modulation, which is another method used to extend the signal power even further.


Both the parabolic wifi antenna and the grid antenna are supported by the base element and it acts as a resonator. Grid antennas usually have a center element and support two horizontal lines. These are often used as point-to-point antennas or wireless bridges. In the case of the parabolic wifi antenna the center element is supported by three parallel wires which are connected to a grounded point.


Yagi wifi antenna functions in much the same way as a parabolic wifi antenna. It too takes advantage of radio waves to transmit signals. In the case of the yagi wifi antenna, the base is supported by a single horizontal line and in some cases this support is supported by a coaxial cable. The transmitted signal then travels along the coaxial cable until it reaches a device that it can be picked up. This means that in the case of the yagi wifi antenna, the transmitted signal travels along a line and not through a single line like the parabolic wifi antenna.


When looking at the differences between the parabolic and the directional  antennas, you will notice that in order for the former to work effectively, the signal needs to travel a very long way. That said, both antennas do not require the same distance to work. While the direction antennas will work well in some situations the parabolic ones are better for others. This is because in many cases you do not want to place a directional antenna on top of a building. With a parabolic antenna you will need to place it in a location where it can benefit from the benefits of the antenna such as when you are going to use it in a building or some other location.


In order for the signal to travel a long distance to the point where it can be picked up, a parabolic antenna has a directional reflector. These directional reflectors are used with the parabolic antennas in order to improve the strength of the transmitted signal. In most cases, a greater strength of the signal is required to allow the signal to be picked up and in a busy area this strength is desirable. For instance, when placing a wifi device in an office space you do not want to have the signal strength to be too low or it will reduce the productivity of the workers. With a directional reflector a strong signal can be transmitted to any part of the office without a reduction in quality.
