CELLFLEX® RF feeder cables are low-loss corrugated coaxial transmission lines designed for reliable RF signal transmission in wireless infrastructure such as cellular base stations, broadcast antennas, and in-building communication systems. They combine foam dielectric insulation, strong shielding, and flexible construction for long-distance and high-power RF connectivity.

Key Benefits

• Low attenuation → preserves signal strength over long distances
• High power handling → suitable for cellular and broadcast transmitters
• Excellent shielding → reduces RF interference and signal leakage
• Flexible but durable design → easier installation than rigid waveguide
• Low Passive Intermodulation (PIM) → important for modern cellular networks (4G/5G)

Typical Specifications

(Example based on common 1/2″ CELLFLEX cable)

Available Cable Sizes

CELLFLEX feeder cables come in multiple diameters depending on power and distance:

Larger cables → lower signal loss but heavier and harder to install.

Frequency Range

Typical operating ranges depend on cable size:

Transmission Line Type

• Coaxial transmission line
• Corrugated copper or aluminum outer conductor
• Foam dielectric insulation
• 50-ohm characteristic impedance

Common Connector Types

Typical connectors used with CELLFLEX cables:

• N-type connectors
• 7/16 DIN connectors
• 4.3-10 connectors
• EIA flange connectors (large cables)

These connectors maintain impedance and shielding for RF transmission.

How to Choose the Right Feeder Cable

When selecting among similar RF feeder cables, consider:

1. Frequency Range

Choose a cable rated above the operating RF frequency (e.g., 5G, LTE, microwave).

2. Cable Loss (Attenuation)

Lower loss is better for long runs.

Rule of thumb:

3. Power Level

Higher transmit power requires larger cables.

4. Installation Environment

• Indoor plenum → flame-retardant jacket
• Outdoor → UV-resistant PE jacket

5. Flexibility Requirements

• Superflex → tight spaces / jumpers
• Low-loss standard → long feedlines

✅ Typical Applications

• Cellular base stations
• Distributed Antenna Systems (DAS)
• Broadcast antennas
• Microwave equipment connections
• Public safety communication systems
