CY Series: Outdoor Low Loss Coaxial Cable
Struggling with outdoor cable degradation and signal loss in harsh environments? AO Microwave’s CY Series outdoor low-loss coaxial cables are built with UV-resistant PUR jackets to prevent weathering. With silver-plated copper shielding and solid PTFE cores, they deliver stable, low-attenuation transmission up to 18 GHz under -40°C to +85°C. Highly durable and flexible, they are optimized for mobile vehicle antennas, phased array radars, and shipboard systems.
Weather-Proof & Low-Loss Coaxial Cables for Harsh Field Deployments
Are you experiencing signal degradation in outdoor RF runs, mechanical wear in high-vibration vehicle antennas, or cable jacket cracking under intense solar UV radiation? AO Microwave’s ruggedized CY Series outdoor low-loss coaxial cables are specifically designed to overcome severe environmental stress, securing your mission-critical communication links in the harshest outdoor conditions.
Built with multi-layer silver-plated copper shielding, solid PTFE dielectrics, and extreme-durability Polyurethane (PUR) jackets, the CY Series offers field-proven reliability that translates to real-world operational advantages:
- Complete Resistance to Environmental Weathering: Encased in highly resilient, UV-resistant and hydrolysis-resistant Polyurethane (PUR) jackets. These jackets withstand continuous solar exposure, humidity, and chemical abrasion across a wide -40°C to +85°C temperature range, eliminating expensive maintenance on remote masts.
- Stable, Low-Loss Transmission up to 18 GHz: Incorporates high-conductivity Silver-Plated Copper (SPC) center conductors and high-dielectric-strength solid PTFE cores. This combination minimizes signal attenuation and maintains tight VSWR over long runs, expanding your system's operational range.
- Superior Interference Rejection (>70 dB): Protected by a three-layer shielding architecture, including a Silver-Plated Copper Foil inner shield, an Aluminum foil interlayer, and a Silver-Plated Copper wire outer braid, blocking stray electromagnetic fields in dense multi-carrier environments.
- Dynamic Flexibility for On-the-Move Vehicles: Supports excellent bend tolerances (static bend radius down to 25 mm for CY460), making them highly suited for tight routing in mobile armored vehicles, military gimbals, and marine mast structures.
Review our detailed physical parameters and attenuation tables below to select the exact CY Series jacket thickness (from 5.00 mm for CY460 to 10.15 mm for CY1000) tailored to protect your high-frequency links from outdoor downtime.
CY Series Coaxial Cable Selection & Engineering Guidelines
When routing coaxial lines for field installations, shipboard units, or vehicle antennas, planning for environmental and mechanical stress is critical to maintain network health:
Matching Jacket OD with Mechanical Clearance
The outer diameter (Jacket OD) of the CY Series corresponds directly to its physical sizing in millimeters (ranging from 5.00 mm for CY460 to 10.15 mm for CY1000). For dense vehicle routing or short jumps, smaller options like CY460/CY520 provide excellent flexibility. For high-power terminal feeds requiring minimum attenuation, larger models like CY1000 provide the necessary performance.
Adhering to Specified Bending Limits
To prevent mechanical damage to the solid PTFE dielectric core during installation, respect the static bending radius (e.g., 25 mm for CY460 up to 51 mm for CY1000). For continuous dynamic motion setups, apply our dynamic bend limits to ensure long-term cable reliability.
Overcoming Critical Outdoor & Field Challenges
Active radars, shipboard networks, and tactical telecommunications operate under brutal conditions. We optimize our CY Series to eliminate common outdoor pain points:
Mitigating UV & Hydrolysis Degradation
Cables installed on outdoor masts or vessel superstructures are constantly exposed to solar UV rays, humidity, and ozone. Standard jackets embrittle and crack over time under these forces. Our CY Series utilizes specialized, UV-stable Polyurethane (PUR) jackets. This compound resists tearing, chemical exposure, and moisture ingress, keeping your hardware protected in the field.
Maintaining Impedance in High-Vibration Systems
During mobile operations, vehicle vibrations can cause solid dielectrics to compress, resulting in impedance mismatches and VSWR fluctuations. AO Microwave uses high-purity solid PTFE dielectrics combined with double silver-plated copper wire braids. This robust design secures the center conductor's alignment, maintaining low VSWR and stable signal transmission under continuous vibration.
