Seriously, how is Yahoo still a thing, anyway? The last time they were actually useful was in the '90's!
You mean, like SONY?
Yep. A physicist trying to explain a balanced line to other physicists, without knowing the word for it.
Haldane would be spinning in his grave.
If the end of the coil that is hanging is grounded (earthed), it becomes an autotransformer. As it's shown, it's a variable inductor and the disconnected end is irrelevant and has no meaningful physical effect at the frequency a spark transmitter could have reached.
This comment seems to get closer to what they actually mean in their scientific paper. But the article about it is garble and the paper might suffer from second-language issues, and a lack of familiarity with the terms used in RF engineering.
Sorry, I was being sarcastic. I happen have built more than one counterpoise.
The point they're missing is grounding of the "asymmetric" half of the antenna, and that's to keep a static charge from building in the antenna that'll zap through your electronics (or you) for safety reasons.
Sometimes. But you're missing what a Counterpoise does.
