Foam Dielectric Radiating Coaxial Cable

  • Longer radiation distance

The low attenuation of RFCL radiating coaxial cable series provides efficient transmission line

The unique design and precise manufacturing process offer the excellent VSWR performance

  • Wide range of operating frequency

Due to the wide range of operating frequency, RFCL radiating coaxial cable series could be applicable to the most wireless applications of the tunnel, underground, and in-building such as FM, DMB, and broadcasting

  • Other advantages of RFCL

Better coupling loss at a specific frequency by optimized slot design\

Longer radiation distance
