After decades of professional antenna modeling with tools like HFSS, CST Studio, and FEKO, Gary recently transitioned to part-time work — and needed a more accessible, cost-effective solution.
His search led him to AN-SOF, where he began exploring its capabilities through the free trial.

🗞 Quick Update: Following feedback from several users, we’ve decided to bring forward the release of the Sommerfeld–Norton ground model in the upcoming AN-SOF v10.5.
This model supports the simulation of dipoles and loops above highly dielectric grounds at very low heights—down to 0.005λ—which is sufficient for most practical applications.
Together with the existing Sommerfeld–Wait Asymptotic model (recommended for conductive grounds), AN-SOF now covers a broad range of ground conditions across typical operating frequencies.
🎉 Celebrating 100 Years of the International Amateur Radio Union (IARU)
April 18, 2025 marks not only World Amateur Radio Day 🎙, but also the centennial of the IARU—a global voice for radio amateurs since 1925. Over the past century, the IARU has played a vital role in promoting innovation, education, and international collaboration across the amateur radio community.
As we honor this milestone, let’s also celebrate the spirit of experimentation that continues to unite hams, engineers, educators, and antenna enthusiasts worldwide.

We are excited to announce the release of AN-SOF 10 🚀, the latest version of our powerful antenna simulation software 📡. Designed with the needs of RF engineers, ham radio enthusiasts, and academic professionals in mind, AN-SOF 10 brings a host of new features and enhancements to streamline your antenna design and analysis workflows.
The image below shows my preliminary results experimenting with DeepSeek-V3 to assist in designing a 3-element Yagi-Uda array for the 10 m band. I requested an output file in NEC format to import into AN-SOF Antenna Simulator. The image displays three iterations where I requested modifications to improve the Front-To-Back (F/B) ratio.
Key Takeaways So Far:
✅ It’s important to start with general requests about the antenna design before refining them with more specific requirements.
✅ In this example, I began with broad prompts:
📏 What are the recommended element lengths and spacings for a Yagi-Uda antenna?
📏 Could you recommend the element lengths and spacings for a 3-element Yagi-Uda antenna for the 10 m band?
✅ Finally, I prompted the AI to generate a complete NEC model 📝.
I’ll be sharing more details soon!
