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.
RG6 is used by cable co's in the USA as a direct overhead drop with no catenary, but they use some kind of compression 'anchor' that wedges the cable rather than the 'curlywurly' dropwire clamps that BT use on their o/h stuff. (I Imagine they'd screw up the RF impedance somewhat)
If you can get a decent 'anchor' at each end (maybe threading thru a hole or similar then clipping) i'd not worry about RG6 overhead. But anything with a solid copper rather than CCS centre core is going to need support for any run of more than a couple of metres
