Antenna Modeling for Beginners - Horizontal Delta Loop (Part 5)

In this episode we move away from verticals and start modelling loop antennas. Using MMANA-GAL, we draw a horizontal delta loop and explore how it behaves compared to a vertical antenna. Along the way we also look at how ground conditions affect antenna performance, and why antennas near salt water can perform dramatically better. In this video we: • Benchmark a vertical antenna at low take-off angles • See how changing ground conductivity affects performance • Draw a horizontal delta loop using the wire editor • Place the feedpoint and model a 4:1 balun • Use wire scaling to tune the antenna to the correct frequency • Compare the far-field plots of a loop and a vertical You’ll also see how loop antennas behave on multiple harmonics, making them useful multiband antennas. In the next episode we’ll convert this into a vertically polarised delta loop and compare the radiation patterns again.
