Miniature Stranded Coax  
Miniature 75Ω Coax for SDI Digital Video  
         
   
  Precision, low-loss coax for digital HDTV, SDI, and analog video transmission. With a 1GHz bandwidth, the Miniature HD series coax series can be used in a variety of digital or analog broadcast, commercial, or residential video applications.

The Miniature HD series utilizes a proprietary gas-injected dielectric that reduces the high frequency attenuation and provides exceptionally low return-loss. The high-purity, solid copper center conductor has a precision overall diameter for exceptional electrical characteristics, while the double foil and braid shield provides broadband rejection from external RF and EMI interference.

Riser Rated, the Miniature coaxial cables have a low friction and easy-to-strip jacket that simplifies cable installation and termination.

FEATURES & BENEFITS
Precision 75Ω Impedance
The characteristic impedance has precision tolerance specifications to prevent impedance mismatching that can lead to reflections, jitter, and bit-errors.
1GHz Bandwidth

Cable bandwidth guarantees SRL, attenuation, and impedance specifications for clear and accurate video transmission.

Gas-injected Dielectric

Proprietary, Nitrogen-injected, blended polyethylene dielectric provides uniform cell structure, crush resistance, and low structural return loss.

100% Swept Test

All reels are swept test to meet or exceed product specification.

UL Rated for Permanent Installation
Outer jacket is UL listed for permanent installation.
