KD

- This is a calculator for a long wire setup in a shielded room to generate electric fields below 30 MHz.
- KD is a factor to calculate Uin: Uin = KD * E (V/M)
- Wire should be much closer to the ceiling than to the floor.
- Use copper tube of 12 - 15 mm for the wire.
- Correct impedance check: voltage measured with oscilloscope at the input and load end should be equal.
