M0ukd antenna calculator It has gone through a few revisions over the years Antennas are a Diamond X-50N mounted about 11 metres above ground for VHF/UHF, and a 20m long doublet fed with 300Ω feeder for HF. 22. Finally, click on the Calculate button for the pure ERP and EIRP. 5:1 at 433MHz with the original SO-239 and PL-259 to N-Type adapter. The document provides a calculator for designing a Quarter Wave Ground Plane antenna, detailing the necessary measurements for the vertical monopole and radials based on frequency and velocity factor. Listed under the Antennas/Antenna Calculators category that is about Calculate and Design Antennas . Don’t know the maths or the theory, but this antenna works as well as a G5RV.
