Random Wire Antenna Calculator

This program helps you to calculate the optimal length of wire for building a random length antenna.

You can find more info on my blog post related to this program: Random-Wire antenna.

Installation

$ pip install randwire

Usage

usage: randwire.py [-h] [-D] [-b BANDS [BANDS ...]] [-f FILE]
                   [-u {meter,feet}] [-c CSV]

Wire length to avoid

optional arguments:
  -h, --help            show this help message and exit
  -D, --debug           Print information useful for debugging
  -b BANDS [BANDS ...], --bands BANDS [BANDS ...]
                        List of bands [default: [40, 20, 15, 10]]
  -f FILE, --file FILE  Graph filename, then extention can be (.png, .pdf,
                        .svg) [default: wire.png]
  -u {meter,feet}, --unit {meter,feet}
                        Wire length [default: meter]
  -c CSV, --csv CSV     Name of the .csv file [default: no_file]

Example

√ % randwire
13:45:27 INFO: Bands: 40, 20, 15, 10
13:45:27 INFO: "wire.png" saved

The program generates an image showing the length of the wire to avoid. The blue blocks represent the length of the wire that might cause tuning problems.
