...least a frequency above 300 Megahertz. We have design that we can propose although you can choose to go with a different design if you believe it would be easier to achieve the desired output. Van de Graaff Basics: Traditional Van de Graaff generators operate by transferring static charge to a conductive dome. The static nature of the charge means there isn’t a well-defined "frequency" in the MHz range. Generating 800 MHz Output: The 800 MHz frequency is in the radiofrequency (RF) spectrum, which would typically be generated using an RF oscillator or transmitter, not a Van de Graaff generator. To integrate this frequency output, the system would need a Van de Graaff generator to work in tandem with RF-generating electronics. Proposed Design Pla...
