Challenge for 2025-05-05 - 2025-05-11:

Category: 🛠️ - Difficulty: 🟠

Simulate an antenna!
Which antenna type did you pick? Which program did you use? How does the process of entering the antenna work in that program? Which are the important parameters you get from the simulation?

Use radials instead of ground screen. Might be fun to simulate in the upcoming HC19 #HamChallenge “simulate an antenna” activity. #HamRadio

Have SW loaded on my ham Win11 machine and ready to explore capabilities/limitations of this package.Here’s a 20m dipole example walk-through that gives good insight into this SW:https://antennasimulator.com/index.php/knowledge-base/complete-workflow-modeling
