Mercury Eco RG6 Foamed PE Coaxial Cable with Aluminium Braid - Brown (100m)

The Mercury Eco RG6 is a 75-ohm coaxial cable with a solid copper-clad steel (CCS) conductor, foam polyethylene dielectric, aluminium/PET foil screen, and aluminium braid, finished in a brown PVC outer sheath. Supplied on a 100m reel with metric markers printed along the cable run, allowing installers to measure and cut to exact lengths without external measuring tools.

Designed for digital TV aerial systems, satellite dish feeds, and CCTV camera runs, the brown sheath provides a discreet alternative to white or black cable where it runs along skirting boards, across timber cladding, or through garden settings. The 6.6mm overall diameter fits standard coaxial cable clips and external ducting. The 75-ohm impedance matches standard F-connectors, satellite receivers, TV aerials, and DVRs without requiring impedance matching transformers.

The foam PE dielectric reduces signal loss compared to solid polyethylene cores, keeping attenuation to 22.2dB per 100m at 1000MHz and 33.3dB per 100m at 2150MHz, which allows satellite signals in the 950-2150MHz band to reach receivers with adequate strength over typical domestic runs of 20-40m. The aluminium braid and foil screen provide 24dB minimum return loss between 5-400MHz, suppressing interference from mains wiring and external RF sources. The solid CCS conductor gives better rigidity than stranded copper for fixed installations where the cable is clipped in place and not subject to repeated flexing.

The 100m reel weighs 3.8kg and the cable has an 83% velocity factor, which affects the physical wavelength of signals travelling through the foam dielectric compared to air. This specification is relevant when calculating stub lengths for phase-matching in distribution amplifier systems or when designing custom-length stubs for filtering applications.

What connectors fit this cable?

Standard RG6 F-connectors, compression or crimp types, fit the 6.6mm outer diameter. The solid CCS conductor accepts push-through compression connectors designed for RG6 cable with 1mm centre pins.

Can this cable be used outdoors?

The brown PVC sheath is suitable for outdoor use in typical UK climates when clipped to walls or run through conduit. For burial or exposed UV environments, additional UV-rated ducting or conduit is recommended to extend cable life.

What's the maximum run length for satellite signals?

At 2150MHz (the upper satellite band), attenuation is 33.3dB per 100m. For a typical satellite LNB output of around 90dBµV and a receiver input sensitivity of 50dBµV, a maximum run of approximately 120m is possible before signal drops below usable levels. Practical installations rarely exceed 50m.

Why brown instead of white or black?

The brown sheath blends against timber cladding, brick, terracotta render, and garden fencing where white or black cable would stand out. It's commonly chosen for external satellite dish feeds on period properties or timber-framed buildings.
