Email: sales 4gltemall.The Yagi or Yagi-Uda antenna gain is particularly useful because it enables all the transmitted power to be directed into the area where it is required, or when used for reception, it enables the maximum signal to be received from the same area.
Coupled to this the fact that it has reduced gain in other directions means that it receives or transmits less signal in other directions thereby reducing the levels of interference.
It is worth understanding that the performance of a passive antenna i. There are many factors that affect the overall Yagi antenna gain. There is a link between the gain and the beamwidth. If the Yagi gain increases, then the beamwidth decreases. This can be reasoned by thinking of the available transmit power.
As there is only a certain amount of power available, to create gain, power must be taken from one direction to put into the main beam. This means that very high gain antennas are very directive. Therefore high gain and narrow beam-width sometimes have to be balanced to provide the optimum performance.
One of the major factors controlling the Yagi antenna gain is the number of elements in the design. However the spacing between the elements also has an effect. The overall performance of the RF antenna very many inter-related variables and as a result many early designs were not able to realise their full potential.
Today computer programmes are used to optimise the designs before they are manufactured and this means that their performance is better than the early designs. Although there is variation between different designs and the way Yagi-Uda antennas are constructed, it is possible to place some very approximate figures for anticipated gain against the number of elements in the design. This can be a useful rule of thumb guide to the expected Yagi antenna gain.
As an additional rule of thumb, once there are around four or five directors, each additional director adds around an extra 1dB of gain for directors up to about 15 or so directors.
The figure falls with the increasing number of directors. This is simply a ratio of the signal level in the forward direction to the reverse direction. This is normally expressed in dB. The front to back ratio for a Yagi antenna, or any antenna for that matter, is normally expressed in decibels. Accordingly it is necessary to take the log 10 for the ratio. The front to back ratio is important in circumstances where interference or coverage in the reverse direction needs to be minimised.
Unfortunately the conditions within the antenna mean that optimisation has to be undertaken for either front to back ratio, or maximum forward gain. Conditions for both features do not coincide, but the front to back ratio can normally be maximised for a small degradation of the forward gain. Gain and beamwidth options for Yagi antenna This means that very high gain antennas are very directive.
Typically a reflector is the first element added in any Yagi design as this gives the most additional gain, often around 4 to 5 dB. Directors are then added. For mid ranges of the number of directors, each director provides very roughly 1 dB of gain.
Typically a wide-spaced beam, i. The most critical element positions are the reflector and first director, as their spacing governs that of any other elements that may be added.
There is certain amount of latitude in the element positions. Yagi gain vs number of elements Although there is variation between different designs and the way Yagi-Uda antennas are constructed, it is possible to place some very approximate figures for anticipated gain against the number of elements in the design.

Los Gatos, CA. My review is of 5G storeA Yagi—Uda antennacommonly known as a Yagi antennais a directional antenna consisting of multiple parallel elements in a line,  usually half-wave dipoles made of metal rods. The reflector element is slightly longer than the driven dipole, whereas the directors are a little shorter.
The waves from the multiple elements superpose and interfere to enhance radiation in a single direction, achieving a very substantial increase in the antenna's gain compared to a simple dipole. The largest and best-known use is as rooftop terrestrial television antennas but it is also used for point-to-point fixed communication links,  in radar antennas,  and for long distance shortwave communication by shortwave broadcasting stations and radio amateurs.
The antenna was invented in by Shintaro Uda of Tohoku Imperial UniversityJapan with a lesser role played by his colleague Hidetsugu Yagi. However the "Yagi" name has become more familiar with the name of Uda often omitted. This appears to have been due to Yagi filing a patent on the idea in Japan without Uda's name in it, and later transferring the patent to the Marconi Company in the UK.
The Yagi—Uda antenna consists of a number of parallel thin rod elements in a line, usually half-wave long, typically supported on a perpendicular crossbar or "boom" along their centers. The directors are slightly shorter than the driven element, while the reflector s are slightly longer.
Conveniently, the dipole parasitic elements have a node point of zero RF voltage at their centre, so they can be attached to a conductive metal support at that point without need of insulation, without disturbing their electrical operation. The gain increases with the number of parasitic elements used.
The Yagi—Uda array in its basic form has very narrow bandwidth, 2—3 percent of the centre frequency. Yagi—Uda antennas used for amateur radio are sometimes designed to operate on multiple bands. These elaborate designs create electrical breaks along each element both sides at which point a parallel LC inductor and capacitor circuit is inserted. This so-called trap has the effect of truncating the element at the higher frequency band, making it approximately a half wavelength in length.
At the lower frequency, the entire element including the remaining inductance due to the trap is close to half-wave resonance, implementing a different Yagi—Uda antenna.
Using a second set of traps, a "triband" antenna can be resonant at three different bands. Given the associated costs of erecting an antenna and rotor system above a tower, the combination of antennas for three amateur bands in one unit is a very practical solution.
The use of traps is not without disadvantages, however, as they reduce the bandwidth of the antenna on the individual bands and reduce the antenna's electrical efficiency and subject the antenna to additional mechanical considerations wind loading, water and insect ingress. Consider a Yagi—Uda consisting of a reflector, driven element and a single director as shown here.
All the other elements are considered parasitic. That is, they reradiate power which they receive from the driven element they also interact with each other. One way of thinking about the operation of such an antenna is to consider a parasitic element to be a normal dipole element of finite diameter fed at its centre, with a short circuit across its feed point. As is well known in transmission line theory, a short circuit reflects all of the incident power degrees out of phase.
So one could as well model the operation of the parasitic element as the superposition of a dipole element receiving power and sending it down a transmission line to a matched load, and a transmitter sending the same amount of power up the transmission line back toward the antenna element.
The elements are given the correct lengths and spacings so that the radio waves radiated by the driven element and those re-radiated by the parasitic elements all arrive at the front of the antenna in-phase, so they superpose and add, increasing signal strength in the forward direction. In other words, the crest of the forward wave from the reflector element reaches the driven element just as the crest of the wave is emitted from that element.
These waves reach the first director element just as the crest of the wave is emitted from that element, and so on. The waves in the reverse direction interfere destructivelycancelling out, so the signal strength radiated in the reverse direction is small.
Thus the antenna radiates a unidirectional beam of radio waves from the front director end of the antenna. While the above qualitative explanation is useful for understanding how parasitic elements can enhance the driven elements' radiation in one direction at the expense of the other, the assumptions used are quite inaccurate.
Since the so-called reflector, the longer parasitic element, has a current whose phase lags that of the driven element, one would expect the directivity to be in the direction of the reflector, opposite of the actual directional pattern of the Yagi—Uda antenna.
