It is for this reason, there have been no fixed-length correction on 23cms to work well or consistently for example. Simple fixed-length correction methods do not give accurate results, especially on 432MHz and up where the errors in this method are accentuated. So why not simply apply ‘correction’ to the Yagi elements? HFSS allows for extremely accurate simulation of the complete antenna including booms, insulators, coax cable and so on this removes a lot of manual confirmation time and uncertainty above the final results. Strength, light weight and low wind-load are qualities required in a Yagi by the modern ham in addition, low noise Quite, symmetrical X-pol/crossed Yagis that work well on both VHF/UHF. InnovAntennas have invested in Ansys HFSS 2020 R2, a fully 3-dimensional mesh-based simulation package to help in the perfection and production of the new OWL and LFA Ultra Yagi of light weight Yagis.
