Technical Features
Low-Loss Performance
Using expanded polyethylene or 83% VoP dielectric material, signal attenuation is significantly reduced, particularly in the 6kHz to 14GHz high-frequency band, where loss performance outperforms traditional RG series cables. High signal propagation speed (VoP up to 85%) reduces latency and energy loss.
Structure and Material Design
Inner Conductor: Copper alloy or silver-plated copper core for enhanced conductivity and oxidation resistance.
Outer Conductor: Multi-shield construction (aluminum tape + braid) with a shielding efficiency ≥90dB, effectively suppressing electromagnetic interference.
Jacket: Black polyethylene or thermoplastic elastomer, UV- and corrosion-resistant, yet flexible and capable of repeated bending (down to a bend radius of 25mm).
Environmental Adaptability
A wide operating temperature range (-40°C to 85°C) makes it suitable for harsh environments such as outdoor base stations and industrial equipment.
