A radio communication tower 35 meter tall is struck by lightning. The antenna is placed at the top of the tower and the electronics at the base of the tower. A cable with solid copper shield connects the electronics with the antenna. It is estimated that about 60% of the lightning current will be flowing through the cable shield. What would be the approximate peak overvoltage appearing at the output port of the electronic circuit (that is voltage between the inner conductor and the shield of the cable at the base of the tower) if the lightning current has a peak amplitude of 50 kA? The shield of the cable has a resistance of 4 mΩ/m and negligible leakage inductance.
