Cost effective — a spark gap is considerably lower in cost than the other suggested methods of prevention. How Spark Transmitters Work The oldest sort of radio transmitter invented by man is the spark gap transmitter. e. A jammer could be built to jam the spectra not used by communications, and instead of hopping to a frequency, it can in theory, be linked with the commo gear and leave a hole in that part of the spectra for communications. Excelitas triggered vacuum gaps are the ideal high-voltage switches for applications where a wide operating voltage range is desired. This is interesting, “Blastwavelabs” bought a portable cell phone jammer from a company called DealExtreme, it appears the jammer ships set to frequencies outside North America but it can be modded to work by turning the trim pots a bit (small potentiometers to tune/trim the voltage)…. In the block diagram, you can see a gap in one wire, it is called as the spark gap. This does not put any stress on the center electrode. A CDI ignition starts by generating a charge and storing it up before sending it out to the spark plug in order to ignite the engine. .
