I need to run coax about 15m to my garage. I was assuming that I would need a catenary wire support but then I saw my telephone cable! So, the question is, do I need the catenary wire? Many thanks.
This depends on the type of coax- then first is the centre stranded or solid core, and then what the core is - they do make copper clad steel, cored coax for dropping down long unsupported spans. Equally, the aluminium cored stuff seems to be useless and fail randomly even clipped on the flat. Stranded copper core is pretty good. (20yr life flapping about up a tree.)
What type of coax is, it, how much RF power are you moving, and what is the cost of a line failure, and how long does it have to last ?
