Impedance d'un dipole
A conductor supplied in the middle has an impedance which depends mainly on its length and its diameter but also on the frequency
Introduction to Transmission Lines
How do you connect a receiver or transmitter to an antenna, Simple a transmission line
La polarisation d'une antenne
The polarization of an antenna is that of the electric field of the wave that it radiates or that it receives in a privileged way, for example through its main lobe
L'antenna Long-Wire
Una comoda antenna multi-banda,pocca spesa minimo ingombro
Les antennes cadre, loop et boucles
There are two families of loop antennas: large loops whose total length is of the order of one wavelength and small loop antennas tuned like oscillating circuits

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
