Programma di calcolo del condensatore
The diagram shows a capacitor with three 4-square-inch plates, separated by 0.25 inches of air. Its calculated capacitance is 7.18 picofarads


Take off angle of horizontal antenna

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
