KATHREIN ERE 01 Coaxial Attenuator 1 dB, F-Male to F-Female, 75 Ohm, 5-2400 MHz

Signal levels in TV, satellite, and cable distribution networks often arrive too hot for receivers, causing overload and pixelation. The KATHREIN ERE 01 coaxial attenuator solves this by reducing the signal by a precise 1 dB, ensuring clean, stable reception without distortion.

Who is it for

Installers and technicians working in CATV, SMATV, and satellite systems who need a compact, inline solution to fine-tune signal levels. It is ideal for balancing multiple drops or compensating for short cable runs where signal is excessive.

Main features

• Fixed 1 dB attenuation for precise signal reduction
• F-male to F-female connectors for easy inline installation
• 75 Ohm impedance matches standard RF distribution equipment
• Wide frequency range 5–2400 MHz covers TV, SAT, and cable bands
• Nickel-plated brass housing for durability and corrosion resistance
• High shielding effectiveness >100 dB prevents interference
• Low VSWR <1.2 ensures minimal signal reflection
• DC blocking prevents voltage from passing through

Tips

Install the attenuator as close to the receiver as possible for best results. For larger reductions, multiple attenuators can be cascaded, but ensure total attenuation does not drop the signal below the receiver's minimum input level.
