Tendril HD-SDI is a coiled coaxial cable for use with HD signals and beyond. Tendril HD-SDI is 12" retracted and can stretch to 48". This cable features a 90 degree BNC male plug on both sides.
As with any coiled coaxial RF cable, it isn't recommended to use where long runs of cable will be used in the same chain. This is because coiling a coaxial RF cable changes the impedance/capacitance. This is true for all brands of coiled coaxial cable. Over time, the expansion and retraction of the cable may also affect the electrical properties of the assembly.
