1-5/8 Inch D Leaky Cable

A 1-5/8 inch D Leaky Cable is the pinnacle of radiating cable technology. It is a ized tool for extreme-distance, ultra-low-loss applications where maximum reliability and minimal active components are the primary design goals. Its key advantage is enabling wireless coverage in the largest and most challenging environments on earth by allowing signals to travel the longest possible distance with the least amount of loss. The very high initial cost is a strategic investment that is amortized over the life of the project through drastically reduced amplifier counts, simplified maintenance, and unparalleled system reliability.

1.Ultra-Low Attenuation (Lowest Signal Loss): This is the defining feature. The very large diameter of 1-5/8" D Leaky Cable results in the absolute lowest attenuation (signal loss per 100 meters) available in any standard radiating cable. It significantly outperforms even the 1-1/4" cable, ely at higher frequencies.
2.Highest Power Handling Capacity: The immense cross-sectional area allows it to handle extremely high levels of transmit power from amplifiers. This is critical for systems that combine the full output of multiple cellular operators and public safety networks onto a single backbone.
3. Precision Engineered Radiation Pattern: The slots in the outer conductor are meticulously designed and tested to provide a predictable, uniform, and optimized Coupling Loss across its specified ultra-wide frequency range.
4.Heavy Gauge Corrugated Copper Construction: Built for maximum durability and performance over decades.
a.Extreme Tensile Strength: Designed to be suspended under its own weight over incredibly long distances (e.g., deep mine shafts) without stretching or failing.
b.Maximum Crush Resistance: Offers superior protection in the most rugged environments.
c. Perfect Moisture Barrier: The continuous copper sheath provides an impeccable hermetic seal against moisture, humidity, and corrosive elements.
5.Optimized for Very High Frequencies:Its ultra-low-loss characteristic is most critical and noticeable at high frequencies (e.g., 1800 MHz, 2100 MHz, 2600 MHz, and 3.5 GHz for 5G), where signal loss in smaller cables would be prohibitively high.

6.Specialized Safety Jacket: Always furnished with Flame Retardant, Low Smoke Zero Halogen (FR-LSZH) jacket as a mandatory safety requirement for use in tunnels, mines, and other public infrastructure.

1. Maximum Possible Distance Between Amplifiers: This is the single most important advantage. Its exceptionally low attenuation allows the RF signal to travel farther than any other cable before needing a boost.
Result: It requires the absolute fewest number of repeater stations. This drastically reduces system complexity, potential points of failure, and the long-term operational and maintenance costs associated with active components. This benefit often outweighs the higher initial cable cost.

2. The Solution for "Extreme" Applications: It is the undisputed choice for:
a. The world's longest tunnels (e.g., sub-sea tunnels, trans-alpine tunnels over 15 km / 9 miles).
b. The deepest mine shafts and hoistways, where cable runs are extremely long, vertical, and highly inaccessible for maintenance.
c. Covering vast areas from a single feed point with minimal infrastructure.
3. Unrivaled Multi-System Capability: Its massive power handling and bandwidth make it the ultimate backbone for dense, multi-operator systems:
a.Combining full-power signals from multiple cellular carriers (2G, 3G, 4G, 5G) simultaneously.
b.Hosting high-power mission-critical services (Public Safety, TETRA, P25).
c."Future-proofing" a facility for next-generation high-bandwidth technologies.
4. Ultimate System Reliability: With the minimum number of amplifiers and active components in the system, the overall system reliability and uptime are maximized. This is a critical safety and operational feature for environments where communication failure is not an option.
5. Superior High-Frequency Performance : As network technology evolves towards higher-frequency spectrum (e.g., C-Band for 5G), the 1-5/8" cable is the only choice to ensure these signals can be distributed over long distances without excessive loss.
6. Durability for a Multi-Decade Lifespan: Engineered as a permanent infrastructure asset, it is designed to last for the entire lifespan of a tunnel or mine with minimal maintenance, providing an excellent long-term return on investment.
