Title: Grow An Antenna ... from Seeds
Amateur antennas are universally made of metal conductors, often made by "bending metal." Trees, shrubs, buildings and other objects near an antenna, are regarded as nuisances that reduce an antenna's performance by distorting its pattern or adding unknown losses. Antenna modeling software is viewed as incapable of modeling such effects. In this presentation K6OIK will reveal how popular thin-wire antenna modeling programs EZNEC, 4nec2, MiniNEC, and MMANA-GAL can be used to model dielectric objects. A surprise is that trees can do more than just support an antenna. They can be an effective part of an antenna. In a detailed study, K6OIK will show how to landscape an antenna farm for improved performance - what seeds to plant and where to plant them!
