Original coax standard for broadcast or production quality analog video applications. The precision coax series features a 20 gage solid (or 22 gage stranded) center conductor and solid polyethylene dielectric for low attenuation, tight tolerance 75 Ohm impedance, and 1GHz bandwidth. The precision coax series is ideal when extra durability is desired or for existing installations that still utilize the precision cable format. For digital video or new analog video installations, the High Definition coax series is recommended due to the increased bandwidth, lower attenuation, and greater ease of termination.
