All aspects of the antenna are factored into the design Any such correction would be percentage based with a lower percentage being needed for first and last elements.Ī 70cms LFA Yagi as presented within Ansys HFSS showing all aspects of the antenna being factored into the modelĪ 70cms Ultra Yagi from the front in Ansys HFSS with ferrite core balun attached. This way no 'correction' needs to be added, the exact element lengths are given within the software which in our case is the World's leader and most expensive simulation package available today Ansys HFSS.Ī 'Fixed' length correction such as forumlas given by K1FO and DL6WU, will NOT replicate a wires only model to real world antenna. Elements, boom, insulators, feedpoint and even coax cable being connected to the model. In order for a low noise VHF or UHF Yagi modelled in software to stay low noise when built, the whole antenna needs to be modelled, optimised and finalised as it will be built. In a nutshell, Yagi Calculator can play a major role for engineers, telecom designers, students, teachers and even for hobbyists, delivering accurate results in a fast manner.A Super Low Noise Yagi for serious DX and EME applications - 2020 LFA- Ultra light weight and strong! Ideal for SSB, CW and Data modes such as FT8, FT4, JT65 and more! The results are displayed in a separate window, with the possibility to export them to an output file or to send them to the print queue.Īlso included in the application are a set of utilities that can assist engineers in various calculations, such as the gain or the stacking of an antenna, as well as its impedance or SWR factor. The design of a new antenna can start right away using the dedicated menu once you select the antenna model, set the frequency, diameter, dipole gap, number of directors, boom type, as well details related to the construction of the reflector and dipole, you may press the ‘Calculate’ button. Developers of such applications often make a compromise on looks, but compensate through functionality.

Yagi Calculator is characterized by a basic and simple appearance, which is not uncommon for this type of software. With the aid of an application such as Yagi Calculator, results are delivered automatically, the only necessary effort being the input of various dimensions and specifications that are characteristic to this type of antenna. Yagi Calculator is a science application that targets designers of Yagi antennas, being capable of performing calculations for a given model automatically, based on the parameters defined by the user.Įngineers have a hard time designing antenna prototypes using traditional methods, compromising on productivity and efficiency a whole lot.
