ACT Cabo coaxial RG58 50 Ohm 100 m preto RG58ZT

The ACT RG58ZT is a 100-metre RG58 coaxial cable with a 50 Ohm impedance, built for reliable signal transmission in radio frequency applications. Its tinned copper braid shielding with over 95% coverage and solid polyethylene dielectric ensure consistent performance, while the black PVC jacket provides durability and flexibility for routing in various environments.

Highlights

• 50 Ohm impedance for standard RF systems
• 100 m length on a spool for custom installations
• Stranded tinned copper inner conductor (20 AWG) for flexibility
• Braided tinned copper shield with >95% coverage
• Solid polyethylene (PE) dielectric for stable signal velocity
• Black PVC outer jacket for protection and easy identification
• Operating temperature range from -20°C to +70°C

In daily use

This cable is suitable for antenna feeds, radio equipment interconnects, and low-power RF signal distribution where a 50 Ohm characteristic impedance is required. The 100-metre bulk length allows custom cutting and connector termination on site, making it a practical choice for installers and hobbyists.
