Product Overview

When in-building wireless systems require both plenum-rated performance and enhanced mechanical protection, standard coaxial cable may not be enough.

RFS PlenumShield™ combines the proven RF performance of ClearFill®Line air-dielectric coaxial cable with factory-installed metal armor, providing a robust solution for Distributed Antenna Systems (DAS), Public Safety (ERCES/ERRCS), and other mission-critical wireless applications.

Designed to simplify installations while helping protect the cable from physical damage, PlenumShield™ is an ideal choice for commercial buildings, healthcare facilities, transportation hubs, and other demanding indoor environments.

Why Choose PlenumShield™?

Enhanced Mechanical Protection

Factory-installed metal armor helps protect the cable from impact, abrasion, and accidental damage without compromising RF performance.

Plenum-Rated Construction

CMP-rated for installation in environmental air-handling spaces while maintaining the low-loss performance of ClearFill®Line coaxial cable.

Simplified Installation
