Belden 8259 010, RG 58A U Coax 50 OHMS Black

Belden 8259 010 is a 50 Ohm wireless transmission coax in the RG-58A/U form factor, built with a 20 AWG (19x33) TC - Tinned Copper stranded conductor. It uses PE-Polyethylene (Solid) dielectric insulation and a 95% Tinned Copper (TC) braid shield. A black PVC-Polyvinyl Chloride jacket maintains a compact 0.193 in (4.90 mm) nominal overall diameter.

Key Features
