Description

HUBERSUHNERLogo

Flexible RF cable equal to LMR® 400 UltraFlex

The SPUMA product family provides flexible cable solutions equal to LMR® products (eg. LMR400-UF) and stands for its extremely low loss. These cables are free of halogen and offer excellent electrical performance, especially an outstanding return loss (VSWR). SPUMA cables are designed for applications up to 6GHz and offer great opportunities in appliances like communication, transportation and defence.

Features and benefits:

  • Very low loss (attenuation) up to 3 GHz
  • High screening effectiveness
  • Less price
  • Excellent return loss (VSWR)
  • Flexible cable

Applications

  • Communication
  • Industrial and Railway
  • Defence
  • Mining
