RG 0.81mm Cable (RG-402): A Versatile Coaxial Cable

RG 0.81mm cable, also known as RG-402, is a popular coaxial cable characterized by its small diameter and flexible nature. It is widely used in various applications due to its balance between performance and ease of installation.

Key Specifications:

\r
• Nominal Impedance: 50 ohms
\r
• Inner Conductor Diameter: 0.81 mm (approximately 0.032 inches)
\r
• Outer Conductor Diameter: 2.54 mm (approximately 0.1 inches)
\r
• Dielectric: Polyethylene (PE)
\r
• Jacket: Polyvinyl Chloride (PVC)
\r
• Operating Frequency: Typically ranges from 100 MHz to 1 GHz
\r
