Description
The 3/8″ feeder cable is engineered to provide a “middle-ground” solution for RF engineers. It utilizes a physically foamed Polyethylene (PE) dielectric and a corrugated copper outer shield to ensure a high velocity of propagation and minimal signal leakage (>120 dB shielding).
It is available in both Standard and Superflexible versions. The Superflex variant is particularly popular for connecting Remote Radio Heads (RRH) to antennas on crowded towers, as it allows for tight bends without kinking the outer conductor or degrading the Passive Intermodulation (PIM) performance.
Key Technical Advantages
-
Balanced Performance: Offers significantly lower loss than 1/4″ cable while remaining easier to route and lighter than 1/2″ cable.
-
High Frequency Range: Efficiently supports frequencies up to 13.5 GHz, covering all major 4G and 5G Sub-6GHz bands.
-
Low Intermodulation: The solid corrugated outer conductor ensures the low PIM levels required for high-speed multi-carrier cellular networks.
-
Environmental Resistance: Encased in a UV-resistant PE or LSZH (Low Smoke Zero Halogen) jacket, making it suitable for rooftops, towers, and tunnel installations.
-
Excellent Shielding: Provides 100% coverage, preventing signal ingress/egress in high-interference environments.
