Applications:
RG-214/U coaxial cables are commonly used for broadband transmission of radio, TV, video, and data signals. They are suitable for installations requiring low attenuation and minimal signal distortion, making them ideal for radio signal transmission over longer distances. The low-density polyethylene insulation ensures high-speed signal diffusion and flexibility during installation. These cables are recommended for indoor applications and can be used outdoors only when adequately protected against sunlight.
