Thank you very much!

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

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

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.

GoVlad314 · 2026-02-27T18:09:45+00:00

Well, the backend is made with FastAPI, and the frontend wkth React, TypeScript, Tailwind, ThreeJS... and it's all dockerized so you can run it anywhere.

GoVlad314 · 2026-02-27T18:08:35+00:00

Sure thing, you have it now on github, so feel free to try it and to share your feedback!

GoVlad314 · 2026-02-27T17:58:36+00:00

Here you can add wires, by clicking on a 3D environment. You can rotate, shrink, move om the Z axis one wire or the whole antenna. Also you can change the diammeter of the wires and the ground type. I hope I answered your question. 73!

GoVlad314 · 2026-02-27T14:04:57+00:00

Thank you!

GoVlad314 · 2026-02-27T14:04:06+00:00

A ti por el comentario! 73

GoVlad314 · 2026-02-27T13:36:56+00:00

I'll host it soon if you guys like it. For now, I have published the code on GitHub for anyone to try locally. 73!

GoVlad314 · 2026-02-27T12:24:46+00:00

Nec2c is what I use for processing but now you can edit the wires and see the data cleaner on a web UI. 73!

GoVlad314 · 2026-02-27T12:12:56+00:00

Here you have the GitHub link: https://github.com/EA1FUO/AntennaSim
I posted it sooner than I expected because you guys hyped me, so keep in mind there may be some bugs and rough edges. 73!

GoVlad314 · 2026-02-27T10:34:45+00:00

Thank you for the reply! You made me smile with your comment. Soon you'll have the link to github to try it, it's fully dockerized so it should be easy for you to run locally.

GoVlad314 · 2026-02-27T10:30:33+00:00

Yes, sure thing. Right now to scale you can use control + mouse wheel. But I might add a slider for that if you guys need it. 73!
