Antenna Kathrein KAZ 11 Black Silver

The Kathrein KAZ 11 Black Silver surge protector is designed to protect system components in antenna reception and distribution systems from transient overvoltages. It provides fine protection by reducing overvoltages between the inner conductor and outer conductor to safe values and is suitable for satellite, CATV and terrestrial reception and distribution systems. The unit supports passage of 22 kHz and DiSEqC signals, has an impedance of 75 Ω and is intended for indoor mounting. It conforms to EN 61643-21 and is equipped with F connectors. Compact dimensions: 90 × 76 × 36 mm.

Advantages

The device offers targeted protection close to the equipment to be protected, limits transient overvoltages to safe levels, maintains signal integrity for 22 kHz and DiSEqC control signals, and complies with EN 61643-21. Its 75 Ω impedance and F-connector compatibility make it suitable for common antenna and distribution installations.

How to use

Install the KAZ 11 as close as possible to the equipment you want to protect (for example near the receiver, amplifier or splitter). Connect the coaxial line using F connectors, ensuring correct impedance matching (75 Ω). Verify that the device orientation and mounting position comply with indoor installation requirements. The protector allows control signals (22 kHz and DiSEqC) to pass through without interruption.

Recommendations

Position the surge protector immediately upstream of the protected device and check connectors for corrosion or damage before installation. For full system protection, combine with appropriate grounding and follow local installation standards and the EN 61643-21 guidance.
