Mystery of the Broom Antenna


Benjamin Franklin


January 17, 1706

April 17, 1790


Giovanni Battista Beccaria

1716 - 1781


Another portrait of Benjamin Franklin


Lomonosov and Rihman  studied the atmospheric electricity with help of a high raised metal rod, Rihman was killed during the experiments by a lighting. Giovanni Beccaria such metal road firstly connected to the earth , then connected to electroscope and then observed the reaction of the device. So, he could measure the potential of the road compare to ground. Beccaria called the metal road and electroscope “meter of the good weather.”


I tried to repeat Beccaria’s experiment. To my new installed 30- meter length antenna I  connected an electroscope. While several minutes potential at the electroscope was raised to 1,500 Volts, then something clicked on my antenna (I believe some insulator sparked) and the electroscope was discharged. It happened periodically.
