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 |
| 2025-04-06 16:15:53 | n8dmt@mastodon.radio | 18 | Working on it... | HC19 Had a chance to try out free AN-SOF antenna simulation SW while modeling a vertical over ground plane and a free-space dipole. Both models worked out well and confirmed 1) SW works as advertised, and 2) have not forgotten everything learned in the past about antenna modeling. Plan is to put together a write-up/posting on my QSL.net/n8dmt web page after copying over screen captures from my Win11 ham computer. SW is reasonably easy to use (with a little guidance). #HamRadio |

E.g. ‘Is there a software that can run on a Mac or do I need to look for a Windows version?’, ‘Can I model an EFHW and how will that help with an EFHW setup at my QTH?’, ‘Do I start with the bands that I want to get on the air like 40m, 30m or 10m?’, ‘Do I just start simple and build from there?’, etc. First step is to find the software. #hamchallenge HC19 @hamchallenge |
