For the 19th challenge, 'Simulate an antenna!’, I have few points to review and decide. 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
