Introduction To Magnetic Loop Antennas
This style of antenna is often used for direction finding and has a sharp reception null when turned broadside to the incoming magnetic field
Les Loop en LF et VLF
While a wired antenna is sensitive to the electric field, a loop captures the magnetic field
Loop Magnetica
Cerchione da bicicletta da 64cm di diamtetro senza raggi,un condensatore variabile 2X 350 pF,un condensatore variabile per i 10-15 metri da 50pF
Loop per ricezione 160m
Ho voluto provare un'antenna per la sola ricezione. Si tratta di un loop magnetico quadrato, di 152 cm di lato, che ho costruito seguendo le indicazioni di KC2TX

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening facto
