[QUOTE="archive10, post: 1030062"] what and where do you want it used? If outside usage, it's better to use PE-sheathed cable (black, shiny, stiffer stuff). The PVC (white) sheath will crack from UV-exposure, and let moisture in. Especially if repeatedly bent in a motorised installation. Dual cable can be simulated by two lengths of single cable tied together with self-amalgamating tape. Also, the thicker the cable the less loss you will have. 4mm dual-shielded cable as suggested above is inferior to 7mm dual-shielded cable. For 30m runs I would consider triple-shielded cable. Even better full-copper core, not jut copper-clad steel. Finally, use proper connectors - compression connectors give a much tighter connection (both RF and water) than screw-on types. For outside use they are really an insurance against moist and noise ingression. They come in booth tool-requiring (PPC etc) and finger-only versions (Cablecon). [/QUOTE]
