Novidade mundial: Antena radiogonométrica para campos magnéticos de Aaronia MagnoTRACKER
The great patent pending idea on this antenna is that you can expand the sensitivity by simply screwing additional gain elements to it. This rises the gain and sensitivity to an almost unlimited maximum at the same time the directivity get even better.
You can use the antenna for the full frequency range of 1Hz to 9kHz without any adjustment. Simply connect it via SMA cable to your Receiver, Spectrum Analyzer, Oscilloscope, Power Meter etc.
Finding bugs or disturbing signals was never that simply and efficient.
