Belden 1675A TIN, Coax 50 Ohm Microwave Cable 14 AWG TFE CU FS BRD Tinned

Description
Belden 1675A TIN is a conformable 50 Ohm coax built to RG type: 401 construction with a 14 AWG solid SCCS - Silvered Copper Covered Steel conductor and PTFE - Polytetrafluoroethylene insulation. This unjacketed coax uses dual shielding with 100% Bare Copper (BC) tape and a 100% Tinned Copper (TC + Tin Filled) braid. It has a nominal Overall Cable Diameter (nominal) of 0.246 in (6.25 mm) and an operating range of -70°C To +200°C. Electrical performance details include specified VSWR, attenuation, and power rating values across 400 MHz to 18000 MHz.
