7/8” Feeder Cable

Description

The 7/8″ feeder is designed for long vertical runs where signal integrity is paramount. Its large diameter significantly reduces resistive losses, allowing high-frequency signals to travel over 100+ meters with minimal degradation. It utilizes a physically foamed Polyethylene (PE) dielectric and a solid corrugated copper outer conductor, providing shielding effectiveness of >120 dB.

While its size makes it less flexible than 1/2″ cables, it is built for extreme environmental resilience. Typically jacketed in UV-resistant Black PE, these cables are rated for a service life exceeding 20 years in the harshest outdoor conditions, maintaining stable Passive Intermodulation (PIM) performance even under heavy wind loads.

Key Technical Advantages

• Ultra-Low Attenuation: Offers the lowest loss profile among standard macro feeders, losing as little as ~3.5 – 4.0 dB per 100 meters at 900 MHz.

• Massive Power Capacity: Capable of handling peak power ratings up to ~90 kW, making it suitable for high-output multi-carrier base stations.

• PIM Excellence: The solid corrugated shield ensures the extremely low Passive Intermodulation required for high-capacity 4G and 5G networks.

• Structural Integrity: Designed to withstand significant mechanical stress, including high ice loads and wind speeds common on cellular towers.

• Universal Standards: Compatible with standard 7/16 DIN, N-Type, and 4.3-10 connectors used in global telecommunications infrastructure.

Key Features

• Impedance: 50 Ohm (Standard).

• Outer Diameter: ~27.5mm to 28.0mm.
