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.
Damn, I wish I would have patented that and all its quantum magic...
I noticed that my vertical transmitting antenna often works better if I connect a horizontal wire about the same length as the antenna to ground at its base! The wire isn't connected to the transmitting side of the circuit at all! And how well it works varies depending on the length! Obviously there is some deus ex machina at work here...
I also had a problem, while on Comcast, where my computer waking up from hibernation would not be able to resolve DNS for several minutes. I'd be able to ping numeric IP addresses including Google's DNS servers, which I'd set the machine to use. But it would be several minutes before I could resolve names. That problem went away completely when I switched off Comcast.
So I'm getting gigabit speeds for $59 a month from an ISP that doesn't have the reputation for fuckery that your ISP probably does. Seems worth it to me.
Clearly you missed the bit where they invoked quantum mechanics, surely that explains away all the inaccuracies, like the fact you can already buy chip scale dielectric antennas
The thing that I really hate about Innovation Stories is that the reporter invariably doesn't understand what's going on, and invariably is easily convinced that The Obviiously Very Technical People have some very valuable invention.
Marconi's connection to the center tap of a coil with one end not connected worked by broken symmetry? Really? It wasn't just a method of tuning a coil to the correct reactance for a particular frequency?
The hardest part of climbing the ladder of success is getting through the crowd at the bottom.
