RF-LLX-CL 7/8" SHF1

Variant:

Radiating coaxial antenna cable for maritime, building, and tunnel installations where conventional radio coverage
is limited. RF‑LLX‑CL supports wideband frequency operation and enables uniform RF signal coupling along the cable,
making it suitable for communication systems with extended frequency range requirements.
