There are several mounting options when it comes to installing signal booster antennas. The easiest one is an omnidirectional antenna which is basically you standing up like a pole. It is a set it and forget it method where you do not have to worry about in which direction the antenna is facing or in which direction the cell phone tower is facing your antenna. The Omni directional antenna is an antenna that is most commonly used because of this ease with which it could be set up in a moment’s notice however the drawback to that convenience is that this antenna works well in places where you have very good cell phone signal available.
Diffrent Types OF Antennas
In locations where the cell phone signal is pretty intermittent are sketchy at best. The antenna of choice is a yagi directional antenna .A yagi antenna has several elements called reflectors mounted on a pole vertically. The yagi antenna receives and transmits signals in different phases. Did your mind by their element links Denison’s wants to change the radiation pattern they’re also called beam antennas due to their ability to focus the direction in which they can transmit and receive signals.
They are used in high frequency, very high frequency and ultra high frequency band applications sometimes they can reach up to 20 DBI in the unidirectional pattern. The yagi antenna operates in what’s called linear polarization. In physics linear polarization is a Bend magnetic field that is perpendicular to the field in which the signal is propagated. one of the best known application for this kind of antenna is your common television very popular in rural areas where the distance between a broadcast station and the receiver which is your television unit is very far and in such applications yagi antenna can focus its ability to harness all the available signal at a given location and deliver it to the device which in this case is your television.
History Of Yagi Antenna
The yagi antenna was invented in 1926 in Japan By Shintaro Uda. yagi antennas very widely used in World War II in the Japanese radar systems. The vertical poles in yagi antenna are called parasitic elements these parasitic elements are cut at a defined length and they are spaced equally from each other .The applications R4 have wide range of uses they typically use what it’s called traps the yagi antenna is designed so that it traps the frequency using a paddle inductor and capacitor in the circuit. The Trap basically truncates the frequency of the signal at a particular bandwidth. this is how a yagi antenna works great for a particular frequency. The range of a yagi antenna frequency is limited compared to an omnidirectional antenna; however the strength operation in that frequency is multi-fold compared to the omnidirectional antenna. Like we mentioned before, the yagi antenna has a drive element and a parasitic element is the only element in the antenna that actually gets excited by electrical signal. the parasitic elements react to drive elements and propagate from one element to another increasing the signal strength in the direction in which it is transmitted. The transmission of a signal from one element to another is a synchronized Dance Off signals being propagated from one to another very beautifully. The video where you from each element har constipated with a face delay Des Innocents make sure that the the direction in which transmission is required to happen happens in a constructive phase and the reverse out of face radio waves cancel each other in a destructive manner that way only the signal that is preferred gets transmitted
