Recommended Projects

DidjImp
A utility for calculating the acoustic impedance of an arbitrary circular bore, primarily for didgeridoos.
Yagi-logper symmetric dipole array model
finds exact gain, directivity and input impedance of Yagi or log-periodic antennas (planar symmetric array of cylindrical dipoles, many driven elements) for a range of specified frequencies, integrates 2D for segments on the same element, moment method
QAntenna
QAntenna is able to show antennas in a 3D plot, and calculate it's radiattion pattern. It is capable of working with many antennas at the same time.
LTuner
L-Tuner Simulator is a small application to calculate the input impedance of the L matching network, the impedance of the load (cables + antenna), or to find the Antenna impedance giving the cable length. It was inspired by my MFJ-929 Auto-Tuner.
SARK100 SWR Analyzer
The SARK100 SWR Analyzer (https://sites.google.com/view/sark100) is a measurement instrument which determines antenna system performance across the HF/6M amateur bands through use of automatically collected SWR and complex impedance readings.
