# Moxon

My Moxon rectangle antenna kit: a compact two-element directional antenna on an H-frame of pipes, held together by 3D-printed parts.

## Theory

[How the Moxon works](<https://oe1ebg.at/projects/moxon/theory/index.md>): geometry and dimension names, feed-point impedance, pattern and the limits of the calculator.

## Build and tuning

[Build and tuning guide](<https://oe1ebg.at/projects/moxon/build/index.md>): assemble the kit, then tune it with a NanoVNA, reading the Smith chart at each step.

## 3D parts

[Explore the printed parts in 3D](<https://oe1ebg.at/projects/moxon/parts/index.md>): rotate the released models in your browser and download the print files.

## Calculator

[Open the Moxon calculator](<https://oe1ebg.at/projects/moxon/calculator/index.md>): dimensions for a chosen frequency and wire type, the geometry and a NEC model export. The notebook runs directly in your browser with Voici.
