Antenna yagi calculator

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

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.

Antenna yagi calculator

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. That is assuming an antenna in "free space". All of these things can change the actual length of a half-wavelength dipole. By that he means that, the formulas used will create a yagi design that can be adjusted while the antenna is on the ground, and then placed in operation, without the need for re-tuning. The original information on these antennas did not include data for the WARC bands 12 meters and 17 meters and only included US Imperial dimensions feet and inches. 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. Making small changes in the element lengths, without changing the element diameters, will not cause a problem.

But in practice, thicker booms are used at these frequencies.

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.

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.

Yagi directional antenna design illustration. Installed antennas can be affected by buildings, trees, mast properties, other antennas, ground conditions, and more. That being said, the calculator only deals with a Two Element Yagi that consists of a Driven Element and a parasitic Director. Boom diameter BD in millimeters the diameter of the PVC pipe where the antenna elements will be mounted on. 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. You could certainly use a smaller or larger tubing, or even wire, but the elements would need to be scaled a bit so that the resonent point stays the same. The antenna will still perform well. 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. The details of the 2-element Yagi antenna will be calculated using the equations above, and then annotated on the drawing. Antenna elements diameter ED in millimeters the diameter of the antenna elements.

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

Time moved on and so did operating systems, so the version was an opportunity to convert to a Windows environment and update the information and modify some of the algorithms. Net developer: automating, improving and empowering better business processes. Boom Type Mounting. The calculator creates equal spacing between the elements, which achieves a balance between good bandwidth performance and a decent Ohm match. But in practice, thicker booms are used at these frequencies. There are a variety of matching devices that can be used see my web page on Yagi Matching. With a metal boom, a local thickening of the antenna elements occurs at the place of installation on the boom. Of particular importance is the feed impedance. 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. To maintain its electrical length, the element must be physically lengthened.
