Aerials are one of the most unprotected as well as exposed elements in lightning discharges due to their placement. Even if an external
lightning protection system exists is present the discharge secondary effects can still affect TV or RF signals. For this the revolutionary ATFREQ Surge Protective Devices should be used.
The ATFREQ Surge Protective Devices can protect the signal cable from damages of TV equipment as well as other equipment such as DVD, Home theaters, etc., by taking the induced as well as conducted surges to the ground. With the help of gas discharge tubes which can withstand 10kA it provides efficient protection against transistory surtentions.
It has optimum coupling with imperceptible loses. Even in the signal with very high frequencies little attenuation is seen. It has a very short response time. The discharge happens in internal encapsulated element, without any external flashes. It has a very small size and provides specific connectors for all applications. The ATFREQ protectors have passed various tests by official as well independent libraries and work with the characteristics of relevant standards. (related in the
