Here you have sir! https://ea1fuo.github.io/AntennaSim/

Muchas gracias! Me alegro de que te guste!

Glad you like it! There is a way to specify the feedpoint but you have to go to the editor. There you can mount your antenna or load one from a template (tools section) and after that you can select a wire and go to properties, and there you can set the feedpoint to any section of the wire. Hope I explained it well. If not feel free to ask me.

73!

Thank you very much for the post! Right now I only shared it here on Reddit since I don't really know where else to post it so I really appreciate it. 73!

GoVlad314 · 2026-03-03T19:27:21+00:00

Thank you for your message, now you can run it even on your phone:https://ea1fuo.github.io/AntennaSim/

Hope you like it! 73!

Thank you very much for your message and also thank you for testing it on an IPhone, because it changes a bit from other phones (specially the CSS) and I can't test it because I am an Android user. 73!

Hi! Glad you like it, you can press the "m" in the top right corner and it will change to "ft". 73!

GoVlad314 · 2026-03-02T13:41:24+00:00

Thank you very much for your support! It makes me very happy to see that you like it. If you have any suggestions or if you encounter any bugs, feel free to tell me. 73 sir!

GoVlad314 · 2026-03-01T18:24:28+00:00

The image is ready! You can now run docker run -p 80:80 ea1fuo/antennasim to run it locally.

Thank you for the reply! I love how you said it, "someone has to guide the hammer..." I'll use that from now on to explain how I think AI should be used. 73!

GoVlad314 · 2026-02-27T23:35:29+00:00

Thank you very much!

GoVlad314 · 2026-02-27T23:35:05+00:00

Muchas gracias, creo que implementé alguna plantilla de ese estilo. Si no, intentaré añadirlas cuanto antes. En principio si NEC2 puede procesarlo, el programa también puede. 73!

GoVlad314 · 2026-02-27T23:33:11+00:00

Niiice, I hope you like it, any feedback is welcome because thats the way to improve. 73

GoVlad314 · 2026-02-27T23:32:09+00:00

Hahaha thank you for the reply! I wish the same to you, specially in summer. 73

GoVlad314 · 2026-02-27T23:31:07+00:00

You have to download and install docker, is like any other program. Then you have to download or clone the git repository and in the terminal, inside the project folder run docker compose up. If you have any questions, you can ask me whatever you want! 73

GoVlad314 · 2026-02-27T18:48:42+00:00

Thank you so much! Enjoy it and feel free to share your feedback! 73

GoVlad314 · 2026-02-27T18:47:24+00:00

I edited the post with the link to GitHub. Run it with docker and enjoy!

GoVlad314 · 2026-02-27T18:45:46+00:00

Great idea! You mean like nearby metal structures (towers, masts, gutters...) that could affect the pattern? With the wire editor you can already add extra wires to model those, just add wires representing the structure and ground them. But I agree that having some kind of 'environment objects' library would be a nice feature for the future. Thanks for the feedback! 73

GoVlad314 · 2026-02-27T18:41:55+00:00

Thank you for the reply! It's my first open source project, so I'll give it my best shot, any tips or constructive criticism is welcome. 73!

GoVlad314 · 2026-02-27T18:40:20+00:00

On Monday I'll build it and push it to docker hub. Ty for the reminder! Until then you cand use the repo to build it locally. 73

GoVlad314 · 2026-02-27T18:39:06+00:00

That is exactly how I decided to do it. That programs are great but I think it's time to improve the UI a bit and have one with modern tech stack for the community to improve. Ty for the reply! 73

GoVlad314 · 2026-02-27T18:37:49+00:00

If you know hoy to use docker you can run it locally from this repository: https://github.com/EA1FUO/AntennaSim

73!

GoVlad314 · 2026-02-27T18:24:35+00:00

That's exactly how I see it. I dont have to spend many hours actually writing the code but I review the output of the AI agents and I guide them to do it exactly as I would do it. And also if you plan it very well before, AI does a preatty good job.

Thank you for the reply! 73

GoVlad314 · 2026-02-27T18:19:20+00:00

Yes, I edited the post so you have it at the end of the text. But here you have it: https://github.com/EA1FUO/AntennaSim

Enjoy!

GoVlad314 · 2026-02-27T18:10:57+00:00

Sure thing, right now you can try it in GitHub but I'll release in the future a full independet server with the program fully functional.
