The dipole program is part of the Yagi-Uda project, a collection of tools designed for the analysis and optimization of Yagi-Uda antennas.To install the Yagi-Uda software suite, including dipole, run the command 'sudo apt install yagiuda'.The dipole program calculates the impedance of a single dipole, making it useful for antenna engineers and amateur radio enthusiasts.The Yagi-Uda project includes additional tools for antenna design and optimization, such as 'first', 'input', 'output', and 'optimise'.
