Antenna yagi calculator

In V3, antenna yagi calculator. 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 antenna yagi calculator are catered for as are different methods of mounting, dimensions of baluns are calculated, there is provision for entering antenna yagi calculator dimensions of an existing DL6WU antenna for optimisation through an external program or to gather information on its gain, beamwidth etc.

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.

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. The antenna will still perform well.

I am not able to check operation with an Apple Computer but Yagi Calculator will not be able to read the Region data. Boom diameter BD in millimeters the diameter of the PVC pipe where the antenna elements will be mounted on Antenna elements diameter ED in millimeters the diameter of the antenna elements The Yagi antenna is a directional antenna using parasitic director and reflector elements to amplify the radio frequency signals from the direction antenna yagi calculator is pointing, 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. 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.

That's OK, as the program isn't going to anything real wierd. Recent hits. Maple Leaf Communications assumes no responsibility for material calculation errors or other deficiencies in the calculator offered here. 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. TAIT programming. 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 spacing required for a parasitic Director is much less than the spacing required for a parasitic Reflector. Boom Diameter. Antenna S-parameters physical sense. Using the driven element as a focal point, the Direction of Maximum Signal is to the right, away from the director. 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. The larger diameter elements increase the SWR bandwidth.

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.

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. 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. DM4YWL interface. The details of the 2-element Yagi antenna will be calculated using the equations above, and then annotated on the drawing. Name required. Of particular importance is the feed impedance. Yagi directional antenna design illustration. A metallic rod that is mounted parallel to the Driven Element , left or right of center. Satellite system. The old output screen appears to the right.
