Mercury Twin SAT/CCTV RG59 Coaxial Cable 75 Ohm Copper Braid - Black 100m

The Mercury twin RG59 coaxial cable runs two independent 75-ohm signal paths in a single outer jacket, each core built around a 0.65mm solid oxygen-free copper conductor, foam-filled polyethylene dielectric, copper foil screen and oxygen-free copper braid. The twin configuration supplies dual or quad LNB satellite installations where two signal runs are needed to a single receiver location, or runs two separate CCTV camera feeds back to a DVR without the need for parallel cable runs.

Designed for outdoor and indoor runs between satellite dishes and set-top boxes, or between CCTV cameras and recording equipment, the cable maintains 75-ohm impedance across the full frequency range from 5MHz to 2150MHz. The dual shielding (foil screen plus copper braid) reduces interference pickup from nearby mains cables, RF sources and wireless signals. Supplied on a 100m reel with metric cut markers printed along the sheath, allowing accurate measurement during installation without needing a separate tape measure.

The foam polyethylene dielectric gives lower signal loss than solid PE alternatives, with attenuation figures of 8.9dB per 100m at 100MHz rising to 42.2dB per 100m at 2150MHz. The black PVC outer sheath has a 5mm diameter per core (approximately 10mm overall width where the two cores sit side by side), giving flexibility for wall clips and conduit routing without being bulky. The 5.7kg reel weight includes the cable only and sits comfortably on typical cable drum stands during installation.

What's the difference between twin coaxial and two separate cables?

Twin coaxial runs two independent signal cores in a single outer jacket, halving the number of cable runs needed during installation and reducing wall clip and conduit usage. Each core is fully shielded independently, so there's no crosstalk between the two signals.

Can this be used for both satellite and CCTV on the same run?

Yes. One core can carry a satellite signal while the other carries a CCTV camera feed, as long as the terminations and equipment at each end are appropriate to the signal type. The 75-ohm impedance suits both applications.

What connectors does this cable use?

RG59 coaxial cable uses standard F-type connectors for satellite installations or BNC connectors for CCTV. Connectors are sold separately and are crimped or compression-fitted onto the stripped cable ends.

Is the cable suitable for outdoor use?

The black PVC sheath provides basic weather protection for outdoor runs, but the cable benefits from being run inside conduit or trunking where exposed to direct UV or standing water. The copper braid and foil screen are not rated for direct burial without additional protection.
