Well it doesn't matter if it's 10 cm or 100 meters foh-stage if the cable is 100 meters...
Maybe I'm misunderstanding something here? Our cables are 100m, endpoint to end point, always worked flawlessly. From what I read from the poster above here it was something like "If you're planning for a 90 meter run, and it turns out you need do run it elsewhere than planned, you might have to go 115m".. We're not running into those situations, as we don't have long runs, and have lots of spare on the reel if we would need to go longer than our pretty standard 50-60 meter runs. 100m is up to spec, and it haven't let us down yet. I don't understand why a standard which is stated from the maker of the equipment used, confirmed by real life usage should suddenly not work unless there's some damage done to the equipment.
