Antenna protection / Coaxial protection / Videosignal protection
These antenna coaxial protectors uses non-radioactive gas discharge tubes to provide very high discharge current without destruction. The use of the gas discharge tube and its particular mounting allow good adaptation to radio and TV reception signals.

Coaxial protection
KO... is a compact coaxial protection where a gas discharge tubes is used as a protective component. It's an isolator at normal condition but when a surge is applied, it becomes practically shortcut. For the use up to 3GHz. Connections: BNC-, N-, UHF- and 7/16-contact. Other connections at request.
Videosignal protection
H30 is a protection especially developed for video signals for instance for video surveillance. Versions for both 50 and 75 Ohm are available.
