Due to their location, aerials are one of the most exposed elements to lightning discharges. Even when an external lightning protection system exists, the discharge secondary effects can affect the television and radiofrequency signals.
ATFREQ surge protection devices protect the signal cable, channelling the induced and conducted surges to ground, thus preventing damage to the communication and TV equipment and the connected devices (DVD, video, decoders, home cinemas etc.)
Effective protection against transitory overvoltages by means of gas discharge tubes able to withstand up to 10 kA.
- Optimum coupling with imperceptible losses. Small attenuation in the signal even for very high frequencies.
- Short response time.
- Does not produce deflagration.
- Small size.
- Specific connectors for each application.
ATFREQ protectors have been tested in official and independent laboratories, obtaining their characteristics according to relevant standards.
Tests certified according to standards: UNE-EN IEC 61643-21
Relevant standards: UNE 21186, NF C 17-102, IEC 62305
Products compliant with EC requirements.
