These cables, or at least the ones I got, were sent in a tight coil that is then flattened and tied with a twist tie, causing even tighter bends. Tight bends supposedly permanently change the cable's RF characteristics by distorting its cross-section where it is bent. I was going to use them for connecting TV antennas with weak output signals to a preamp, but decided not to use them because I can't afford to waste any signal. However, for larger signals and lower frequencies, they're probably fine, unless you mind their kinkiness.
