This is a simple, lightweight C++ command-line tool for designing a Log-Periodic Dipole Array (LPDA) antenna. You provide the desired frequency range and two key design parameters ($\tau$ and $\alpha$ ...

A simple calculator to calculate total attenuation of an antenna grid between 47MHz - 1000MHz. Components and their values are stored inside a txt file which is configurable. You are able to printout ...

Abstract: An electromechanical calculator has been designed for the rapid solution of directional-antenna patterns. After the desired antenna parameters have been set up, the machine automatically ...

At present, portable receivers generally use ferrite rod antennas for LF and MF (below 2 MHz), and whip antennas for HF (up to 30 MHz). Each type has proved effective in its particular application.
