N3OX Python Utilities

This is a personal package of Python utilities for antennas and transmission lines by N3OX. Work in progress.

Contents

• nfanim: Near-field animations using PyNEC NEC-2++ simulations.

• tlcalc: Lossy transmission line calculations. Implements the same transmission line calculations as Owen Duffy's Transmission Line Calculator for use in Jupyter notebooks and other Python scripts.

• plot_tools General matplotlib pyplot setup as well as ARRL-style pattern polar plots (PDF)

• pynec_helpers: Wire input GUI and other helper utilities for working with PyNEC

PyNEC Helpers

Wire Input Widget

This is a GUI wire entry tool using ipywidgets

Wire coordinates and segmentation are entered manually, and calling the WireInput's return_wire_dicts() method returns a list of dicts that can be unpacked into PyNEC's PyNEC.c_geometry.wire method.
