Abstract
An antenna protection device for insertion between sections of an antenna for cutting the passage of low-frequency alternating electric current. The device comprises a non-linear capacitor with capacitor plates connected to the antenna sections. The non-linear capacitor is characterized by a negative low-frequency voltage coefficient, whereby the passage of a high frequency alternating current remains essentially unaffected.
