In this episode we take the delta loop from Part 5 and convert it into a vertically polarised delta loop. Using MMANA-GAL, we build and model a simple mono-band loop and explore how its radiation pattern compares to a vertical antenna.
In this video we:
• Convert a horizontal loop into a vertical loop
• Position the feedpoint for ~100Ω impedance
• Model a quarter-wave matching section (75Ω)
• Use wire scaling to tune the antenna
• Compare low-angle performance (5° take-off)
• Observe the bi-directional radiation pattern
You’ll also see how a vertical delta loop can behave a bit like a broadside array, producing useful gain in two directions.
This is a simple, practical example of how antenna shape and feedpoint position directly affect performance.
In the next episode we’ll move on to modelling an End-Fed Half-Wave (EFHW) antenna.
