Does Heinrich Hertz' apparatus include a proper antenna?

[QUOTE="Silly Questions, post: 6521982, member: 692624"] RE: "Spark discharge is oscillatory": How much oscillation do you get without the Leydon Jar capacitors and other archaic components Hertz used to keep the oscillation going? Or am I misunderstanding that part of the apparatus? "When you say "build a radio" do you mean something which has a DJ and plays music?" I was thinking of a more modest "transmits and receives morse code using sustained oscillations on a reasonably specific frequency", but "radio" I admit was awfully ambiguous. The time between "Hertz" and "these dampened oscillations are for the birds; we need sustained" was much longer than the poorly-written history made it seem. I read about it long ago and have been holding onto some questions. Like the FM question you more than answered it's just been bugging me all this time. The "crystal sets on ships" you mentioned just detected the dampening spark broadcasts of the spark stations, right? Am I right in thinking that just like my great-uncle's crystal set he built as a kid the signal was very faint? How did the detected pulse get translated into readable Morse code? What apparatus and/or circuitry was between the crystal and the Morse output? RE: David Edward Hughes: Fascinating! He seems to have been part of the "it's just induction" gang. The way the history played out one has to explicitly be looking for Maxwell's predicted phenomenon or be duped. A lot of inventors who stumbled across radio chalked it up to induction. It makes Maxwell look all the more brilliant for having predicted radio with no experimental apparatus. [/QUOTE]
