SPUMA-240

Description

Flexible RF cable equal to LMR® 240

The SPUMA product family provides flexible cable solutions equal to LMR® products (eg. LMR240) 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 6 GHz
High screening effectiveness
Less price
Excellent return loss (VSWR)
Flexible cable
Non-halogen (non-toxic) low smoke, flame resistant type available

Applications

Communication
Industrial and Railway
Defence
