Mercury Eco RG6 Air Spaced PE Coaxial Cable - Aluminium Braid White 100m

The Mercury Eco RG6 is a 75 Ohm coaxial cable with an air-spaced polyethylene dielectric, a 1mm solid copper-clad steel conductor, aluminium/PET foil screen, and a 48-strand aluminium braid. The air-spaced dielectric construction reduces signal loss across satellite, digital TV and CCTV frequencies compared to solid-core PE cables, with attenuation ranging from 2.9dB/100m at 5MHz to 33.6dB/100m at 2150MHz.

Designed for outdoor and indoor satellite dish feeds, Freeview/Freesat distribution, and CCTV camera runs where signal integrity matters over longer distances. The 6.6mm outer diameter fits standard F-connectors and compression fittings used in satellite and aerial installations. The white PVC sheath suits visible external runs on rendered or UPVC-clad buildings where black cable would stand out.

The solid copper-clad steel conductor gives tensile strength for overhead or vertical runs while maintaining the conductivity needed for RF signal transmission. The aluminium foil and braid provide dual-layer screening against interference, with the braid adding mechanical protection and a low-impedance earth path. The 100m reel length covers typical domestic satellite or CCTV installations without requiring mid-run joints, which can introduce signal degradation.

Each reel weighs 4.1kg and the cable supports a velocity factor of 83%, meaning signal propagation is 83% of the speed of light in a vacuum. The capacitance of 54pF/m and 75 Ohm impedance match standard satellite receivers, Freeview boxes, and CCTV DVRs without requiring impedance-matching transformers.

What's the advantage of air-spaced dielectric over solid PE?

Air-spaced PE dielectric reduces signal attenuation by introducing air gaps within the insulation layer, which has a lower dielectric constant than solid polyethylene. This results in lower capacitance and better signal retention across the frequency range, particularly noticeable on longer cable runs above 20m.

What connectors does this cable take?

The 6.6mm outer diameter accepts standard RG6 F-connectors, either screw-on or compression types. Compression F-connectors provide a more reliable weatherproof seal for outdoor satellite dish connections.

Can this be used for outdoor installations?

Yes. The white PVC sheath is UV-resistant and rated for external use on building facades, though it should be clipped or secured to prevent wind movement damaging the cable over time. For buried runs, use conduit or ducting to protect the cable from stone damage and water ingress at termination points.

What's the difference between CCS and solid copper conductor?

Copper-clad steel (CCS) has a steel core with a copper outer layer. It provides greater tensile strength for overhead or vertical runs compared to pure copper, while the copper cladding maintains the conductivity needed for RF signal transmission. Pure copper conductors offer marginally lower resistance but are less mechanically robust.
