Antenna cable ShiverPeaks 80203-128-2.5, impedance 50 Ω, length unspecified, max attenuation 100 dB

Antenna cable ShiverPeaks 80203-128-2.5 is a coaxial cable designed for RF and antenna installations where 50 Ω impedance compatibility is required. The cable is intended to provide controlled signal attenuation up to 100 dB and includes features for reducing common-mode currents and improving isolation in antenna feeds. It is suitable for connecting antennas, tuners, receivers and RF test equipment that operate with standard 50 Ω systems and where specific attenuation or isolation characteristics are necessary.

Advantages

The cable provides a high degree of attenuation—specified up to 100 dB—while maintaining a nominal 50 Ω impedance, ensuring predictable behaviour in RF chains. Integrated common-mode suppression helps reduce unwanted radiation and interference on the cable shield, improving system isolation. The construction supports stable electrical characteristics across the intended frequency range and simplifies connections between antennas and RF devices.

Suitable for

• Connecting antennas to receivers and tuners in 50 Ω systems
• RF measurements and test setups requiring controlled attenuation
• Applications needing improved common-mode current suppression and isolation
• Temporary or permanent antenna installations where high attenuation is desired

Key specifications

• Impedance: 50 Ω (nominal)
• Maximum attenuation (connectivity): up to 100 dB
• Function: coaxial antenna/ RF connection with common-mode suppression
• Color: white (outer jacket)
• Typical length: 2.5 m (as indicated by model variant)

How to use

Install the cable by connecting the coaxial connectors securely to the antenna and the receiving or test equipment according to the device manufacturer’s connector type and torque recommendations. Ensure connectors are clean and free of debris before mating. Route the cable to minimise sharp bends and avoid proximity to strong interference sources. If the installation requires weather protection, use appropriate sealing methods at outdoor connections to prevent moisture ingress.

Usage recommendations

For reliable performance, verify system impedance and expected attenuation requirements before installation. Use this cable where additional attenuation or common-mode suppression is needed; for low-loss signal transfer over long distances, choose low-attenuation coaxial alternatives. Periodically inspect connectors and the outer jacket for damage and replace the cable if electrical performance degrades.
