RF-LLX-CL 1/2" 50 SHF2

RF-LLX-CL 1/2" SHF2

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.
