Miniature 23AWG HD/SDI Coax Snake

 

DSM Series

Low-Loss 23AWG Coaxes - Reduced diameter with iower attenuation than other miniature types

4.5 GHz Bandwidth - meets or exceeds SMPTE 292M and 424M standards for HD/SDI

100% Sweep Tested- network analyzer quality control for consistitent performance

Gas-Injected Dielectric - achieves precision electrical performance and mechanical strength

100% Foil + Braid Shield - dual layer shieldng for exceptional broadband RF/EMI rejection

Flexible and UL Rated TPE Jacket - ideal for portable cables or in-wall installation

The DSM series coax snake cables feature precision 4.5GHz miniature 23AWG coaxes for HD/SDI, standard SDI or high resolution video applications. Each coax element meets or exceeds SMPTE 259M, 292M and 424M standards for high-definition digital video formats. Also built for easy termination, the DSM series coaxes have easy-to-strip outer jackets and dielectrics that streamline connector termination. The outer jacket is extruded from a flexible, rugged and abrasion resistant TPE compound that is ideal for portable and staging applications and UL rated for permanent installation.
