This situation surprises me! I took a risk and, after disconnecting the antennas, I touched my leg with the antenna cable (screen and middle vein) - nothing pinches! And that's OK because the antenna ballon is symmetrical with a grounded center and through the cable shield it has a good connection to the "ground field" in the garden. The voltage I sense, approx. 35V, is introduced by the laptop's power supply.
I stated this before, but I thought that grounding the antenna set would remove this potential, but I did not check it. I have to work on it because the power supply of the laptop brings the noise level up to about 2S. Thanks for the advice Ray! Once, in a winter, during a snowstorm, Windom kicked me hard - static electricity!
- delete it after some time, unless, as a warning, move it to the technical thread!
