Tableau des longueurs d'onde par bande
The tables below give for each amateur band and a few other frequencies the full wavelength (300 / f), the half-wave, and the quarter-wavelength
Trasformatori per antenne attive
Chiunque abbia sperimentato l'uso di antenne attive per la ricezione dalle ELF alle HF, avra' avuto modo di confrontarsi con la necessita' di separare galvanicamente l'antenna
What Antenna Should I Use to Hear Jupiter
In order to receive Jupiter above the roar of the galactic background radiation, you are going to need an antenna with some gain directionality. The absolute minimum antenna which will work for you is a dipole cut to the frequency of interest
