Toroidi Amidon: quanto filo per l'avvolgimento, IZ4SJP
Il programma calcola l'induttanza di un avvolgimento monostrato in aria - The program calculates the inductance of a single-layer winding in air
Half-wave Dipole Antenna Calculator
Dipoles antennas are easy to build and can be very effective when placed half a wavelenth or more above ground.Enter the desired operating frequency in megahertz to get a good starting length for a dipole in both feet and meters
