Attenuator Network Pad TechniSat 0001/3145 Silver 20 dB 75 Ω

The TECHNISAT attenuator network pad 0001/3145 Silver provides controlled signal attenuation of 20 dB with a nominal impedance of 75 Ω. Housed in a compact silver enclosure measuring approximately 50 mm × 24 mm × 50 mm, this passive device is intended for insertion into coaxial audio/video signal chains where fixed attenuation is required to reduce signal level without affecting impedance matching. The unit is suitable for professional and consumer installations that demand predictable attenuation and a small physical footprint.

Advantages

This attenuator delivers a stable 20 dB reduction while maintaining the specified 75 Ω impedance to preserve signal integrity. The compact metal casing offers mechanical protection and helps with heat dissipation in continuous use. Its fixed attenuation value simplifies system setup by removing the need for adjustable controls, and the straightforward passive design requires no power source or active components.

Suitable for

• Reducing signal levels in coaxial audio and video lines
• Preventing overload of receivers, tuners, or amplifiers
• Matching signal strengths between different equipment
• Integration in AV distribution panels and test setups

Key specifications

• Attenuation: 20 dB
• Nominal impedance: 75 Ω
• Enclosure color and finish: silver metal housing
• Approximate dimensions: 50 mm (W) × 24 mm (D) × 50 mm (H)
• Passive, no external power required

How to use

Install the attenuator inline between a signal source and the receiving device using compatible 75 Ω coaxial connectors and cables. Ensure connectors are firmly attached and observe correct polarity where applicable. The device is passive, so no power connection is necessary. Verify signal levels after insertion to confirm the 20 dB reduction and adjust system gain as needed to achieve optimal performance.

Recommendations

Use the attenuator in systems designed for 75 Ω impedance to avoid reflections and signal degradation. For critical installations, inspect coaxial connectors for wear and ensure tight mechanical connections. Avoid placing the unit in areas with excessive moisture or high mechanical stress; if extended exposure to outdoor conditions is expected, provide suitable environmental protection.
