Antenna yagi calculator

In V3.

Meserve Yagi Antennas Element. This page has a variety of calculators that can be used to calculate dimensions for practical antennas for 6, 10, 11, 12, 15, 17 and 20 Meter Yagi Antennas. While you may not have the space for a large array, there is a lot to be gained from simple, 2 and 3 Element arrays. Yes, I do include 11 meters. While it is not a ham band, a 2 or 3 element yagi for this band would provide better communication than strapping on a amplifier. All of the equations used on this page are based on the Basic Wavelength Formula , which is shown on the right. But that is quite a bunch of numbers to remember, so the formula is approximated, as shown under the heading the Approximate Wavelength Formula.

This page is intended for users that want to experiment with a yagi design but do notneed all the rhetoric contained on the main Yagi Design Page. This page assumes that you have already read the information on the Yagi Design Page and understand what each of the text boxes and selectors are for. This page minimizes all the clicking, scrolling, and popups but still uses all of the same equations as the main Yagi Design Page. Any changes to the input data is immediately rendered in the design data at the bottom of the page. Any output in a red font is usually a warning that you are trying to do something that it outside the capabilities of the design program. That's OK, as the program isn't going to anything real wierd. However, in extreme cases, you might get odd outputs, like negative numbers or "NAN" listings. Just try not to stray too far from the program capabilities. The main restriction is to keep the required Gain between Other restrictions exist that are frequency dependent. They are listed in the input areas. Use the following entry areas to define your antenna requirements. The page will operate below the lower limits, The Design Information , lower left drawing, is based on your input data from the previous section. The Antenna Dimension , lower right drawing, is based on your design specifications.

For smartphones owners with the Android operating system, the calculation of the Yagi-Uda antenna of the DL6WU design is available in the Cantennator app.

The calculator calculates the Yagi-Uda antenna of the DL6WU design with boom-correction correction for the influence of the load-bearing boom. The antenna is optimized for maximum gain. It is believed that DL6WU antennas, having a very high gain, are less capricious about the presence of outside objects near them and retain their characteristics under any weather conditions. Antenna has a straight center fed half-wave dipole. It is only necessary to choose the material of the internal insulation of the cable. Let's pay special attention to boom-correction.

In V3. File management has received some major work so if you want to maintain old yagi designs you should be aware that these will not work in this version. Although YO files are still produced, Yagi Optimiser is no longer supported by the author. Features of this free but copyrighted program include: calculation of the element length and element spacings of a yagi for a particular frequency, different size materials for boom and elements are catered for as are different methods of mounting, dimensions of baluns are calculated, there is provision for entering the dimensions of an existing DL6WU antenna for optimisation through an external program or to gather information on its gain, beamwidth etc. A handy SWR calculator and feedline loss calculator are included as part of the package. Stacking information is also provided as are estimates of gain. A Helpfile is included that covers many aspects of yagi design as well as helping with the operation of the program. A major change is that the program will now work for users in Regions where the comma is used as a decimal separator. The program checks your region and adjusts accordingly but stores MMANA and YO files with dot separators as this is required by those programs. Before installing this update save your old directories - perhaps change the directory name of your old installation so that you can still run the old version.

While you may not have the space for a large array, there is a lot to be gained from simple, 2 and 3 Element arrays. With the spacing shown, the 2-Element yagi will exhibit 4. It does not need installation. The program on this site was developed in the early 90s as a DOS program. Any output in a red font is usually a warning that you are trying to do something that it outside the capabilities of the design program. The recommendation is that the matching rod is half the thickness of the dipole material, however using the same material as the dipole has minimal effect on the sweet spot. Deviation meter. Acknowledgements Yagi Calculator is a program to assist with the design of long yagi antennas. Round Square. That being said, the calculator only deals with a Two Element Yagi that consists of a Driven Element and a parasitic Director. Antenna elements diameter ED in millimeters the diameter of the antenna elements. Limitation: 0. After processing a large array of practical results, DL6WU derived an empirical correction formula for the lengths of elements passing through a round metal boom.

The calculator calculates the Yagi-Uda antenna of the DL6WU design with boom-correction correction for the influence of the load-bearing boom.

Acknowledgements Yagi Calculator is a program to assist with the design of long yagi antennas. This antenna design calculates a single dipole rod as active element a gamma match would be the simplest way to connect it to 50 Ohm transceivers. However, the best solution should be recognized as the optimization of results in HFSS, since this program does not have the disadvantages inherent in MMANA and allows you to directly take into account the boom-correction. New Products. The reflector is part of the antenna. Second to note about the boom is that it is assumed to be made of non conductive material, like PVC piping. The dropdown selector for Frequency may seem limited but the frequencies available should provide for sufficient bandwidth on all the bands. The page will operate below the lower limits, Reflector Spacing. Their small size, and especially their small prices, will probably surprise you but they are innovative, no-compromise, top-performing products. For best front to back ratio it is recommended that a yagi be constructed with one of the following numbers of elements - 10,14,19,
