Antenna yagi calculator

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, antenna yagi calculator. 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.

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. With a metal boom, a local thickening of the antenna elements occurs at the place of installation on the boom.

Our sister company, Paladin RF, offers a line of high-quality duplexers and filters. Their small size, and especially their small prices, will probably surprise you but they are innovative, no-compromise, top-performing products. Check us out! Check out our fun page for free stuff! Calculate various antenna dimensions, determine best height above the ground, look up coaxial cable properties, check the ideal stripping dimensions for mounting various connectors, and more. Maple Leaf Communications assumes no responsibility for material calculation errors or other deficiencies in the calculator offered here. Installed antennas can be affected by buildings, trees, mast properties, other antennas, ground conditions, and more. Dimensions reported by this calculator should be considered only approximations of the length s of material required. When ordering materials and building your antenna, allow a little extra length and trim as necessary instead of building and installing the antenna before discovering that it is too short. For people who can get them high enough, and have a method for rotating them, Yagi-Uda antennas are among the best choices for DX work. Their directional selectivity and high gain mean quieter received signals, and stronger transmitted signals, than many other antenna options. Yagi-Uda design dimensions can vary significantly with differences in element diameter, boom material, element-to-boom attachment method, and other factors that are ignored by this simple calculator. The calculator creates equal spacing between the elements, which achieves a balance between good bandwidth performance and a decent Ohm match. Experimenters might want to try varying the spacing especially between driven element and director and adding a matching system to achieve different results.

The dropdown selector for Frequency may seem limited but the frequencies available should provide celestron sufficient bandwidth on all the bands. Performs very well antenna yagi calculator can be used for RX and TX purposes. To connect this to 50 Ohm transceivers we need transformers to convert 73 and Ohm to 50 Ohm.

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.

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.

A major change is that the program will now work for users in Regions where the comma is used as a decimal separator.

Antenna elements diameter ED in millimeters the diameter of the antenna elements. If you want to design for a frequency that is different than the ones I provide, you can use the frequency that is closest to your needs and then use my web page on Antenna Scaling. The Design Information , lower left drawing, is based on your input data from the previous section. Long yagis are commonly used from the MHz amateur band to the 2. Maple Leaf Communications assumes no responsibility for material calculation errors or other deficiencies in the calculator offered here. Various antenna applets and particularly the correction factor for square section versus round rods by Kevin Schmidt. You might notice that the drawings only show the Driven Element as solid element, the same as the parasitic elements. Round Square. Boom Correction Init BC. Antenna matching the driven element Gamma match One of the simplest methods of matching a dipole to 50 Ohm coaxial cable. There are important changes in directories with a different system in place to save your files. Do not use aluminium tubing or other metal materials for the boom.. Select Foward Gain or Boom Length. That being said, the calculator only deals with a Two Element Yagi that consists of a Driven Element and a parasitic Director. They are listed in the input areas.

Our sister company, Paladin RF, offers a line of high-quality duplexers and filters.

It does not need installation. The DL6WU yagi is highly regarded as being easy to build with repeatable results, broad bandwidth and a useful pattern. Making small changes in the element lengths, without changing the element diameters, will not cause a problem. Dimensions reported by this calculator should be considered only approximations of the length s of material required. The amount of antenna elements the more elements the more inverse log gain it has and directional beam becomes more narrow. That is assuming an antenna in "free space". If you change the dimensions of the reflector, then all the Their directional selectivity and high gain mean quieter received signals, and stronger transmitted signals, than many other antenna options. Calculator - 3-Element Yagi Use At Your Own Risk Maple Leaf Communications assumes no responsibility for material calculation errors or other deficiencies in the calculator offered here. Reflector Spacing 0. A metallic rod that is mounted parallel to the Driven Element , left or right of center. The more parasitic director elements up to a point added will increase the DB gain and narrow the receptive beam width. All of the equations used on this page are based on the Basic Wavelength Formula , which is shown on the right.
