wishmegood 0 Posted August 7, 2006 Can RG 6 coaxial cable be used for short run, about 20 to 25 metres, on CCTV system? Why the price for RG 6 is cheaper than RG59/U while the former can be used for further distance up to 1000 ft, and the latter could only be used up to 750 ft? Some said the min. distance of a coaxial cable must be 2 inch away from a power cable, is this true for all the conditions if crossing coaxial cable and power cable at 90 deg.? Thanks for outputs.

rapid 0 Posted August 10, 2006 Sure you can use RG-6 for short runs....go for it...unless this is cablevision cable which is why it may be cheaper....then don't. You want RG6/U, copper center conductor and copper braid with 90% shielding (cable tv will use an aluminum braid). This braid shields against electromagnetic interference (EMI). If you are referring to low voltage beside this line....there's no problem. If this is 120ac then you should seperate the cabling running parallel by a few inches....you can cross cable at 90 degrees without any issues. Share this post Link to post Share on other sites
