WebHalf-Wave Dipole Length. ... (65.6 ft) long dipole for 3 wire sizes. Green is 2mm (AWG #12). Yellow is 1mm (AWG #18). Orange is 0.5mm (AWG #24). The blue line is the … WebTo find the half wave, divide that number by two. This will give you the length of each leg of the antenna. Example — 80 meters: If you are operating on 3.8 MHz, dividing 3.8 into 468 gives 123.16 feet over all. To find the half wave, dividing 123.16 feet by 2 gives 61.58 feet for each leg. Cut the wire two or three feet longer so you will ... WebMay 1, 2024 · At the higher frequency bands due to multiple half-wave resonances along the wire length, the azimuth lobe no more remains a well-defined, broad-side oriented, figure-of-8 pattern unlike a regular 1/2λ dipole wire antenna.
