Beginning in 1924, Professor Hidetsugu Yagi and his assistant, Shintaro Uda, designed and constructed a sensitive and highly-directional antenna using closely-coupled parasitic elements. The antenna, which is effective in the higher-frequency ranges, has been important for radar, television and amateur radio. The antenna was timely in the development of short-wave engineering when new tubes permitted higher frequency and more stable outputs. Applications such as amateur radio, point-to-point communication, VHF Radar and television receiving were natural outlets for the Yagi-Uda antenna system. #TechHistory #IEEETechHistory

3moI bought a 2024 Electric Honda Prologue, but it stopped charging and is not working. The dealer refuses to take it back even though this issue occurred just 9 days after purchase. I am now without a car. Thank you, Honda.
