Now you have to remember, this is 10 years before Heinrich Hertz proved the existence of radio waves -- 15 years before Nikola Tesla's four-tuned circuit -- nearly 20 years before Marconi's first broadcast.
Morate imati na umu, kako se to događa 10 godina prije nego je Heinrich Hertz dokazao postojanje radio valova -- 15 godina prije četvero-titrajnog kruga NIkole Tesle -- gotovo 20 godina prije prvog Marconijevog prijenosa.
