CM Series: Low-Loss Communication Coaxial Cable
Facing signal dropouts, weathered cable cracking, or tight routing issues? AO Microwave’s CM Series communication cables protect your network. Encased in rugged, UV-resistant PUR jackets, these low-loss, low-VSWR cables prevent environmental degradation and costly downtime. Highly flexible (static bend radius down to 6.4mm) and built with solid copper/Foam PE cores, they ensure stable transmit power and smooth installation in base stations and vehicle networks up to 10 GHz.
Low-Loss Communication Cables Engineered to Protect Your Network Performance
Are you facing signal dropouts, high maintenance costs from weathered outdoor cabling, or routing difficulties in confined system enclosures? AO Microwave’s upgraded CM Series low-loss communication coaxial cables are specifically designed to resolve these critical operational challenges, ensuring your RF networks run smoothly and cost-effectively.
By focusing on real-world field durability and electrical efficiency, the CM Series brings direct, tangible benefits to your system integrations:
- Maximize Signal Reach & Coverage: Built with high-purity solid copper cores and high-efficiency micro-cellular Foam PE dielectrics. This combination delivers low insertion loss and low VSWR, ensuring maximum transmit power reaches your antenna without wasting energy.
- Reduce Maintenance & Cable Replacement Costs: Encased in highly rugged, UV-resistant Polyurethane (PUR) jackets [1.1.1, 1.2.7]. Operating reliably from -40°C to +85°C, this jacket prevents cracking, water ingress, and environmental degradation, protecting your hardware from expensive outdoor downtime.
- Simplify Tight-Radius, Stress-Free Installation: Engineered with outstanding mechanical flexibility (supporting a static bend radius down to 6.4 mm for CM280). This flexibility allows for effortless routing in complex vehicle conduits and tight cabinets, saving labor time and preventing internal stress damage.
- Ensure Clean, Interference-Free Signals: Equipped with a high-density double-shielded design to deliver a shielding effectiveness of >90 dB. This high isolation prevents crosstalk and blocks external EMI, securing clean signal paths in crowded base station environments.
Review our detailed physical and electrical specification tables below to find the exact CM Series fit—ranging from the ultra-flexible 2.79 mm CM280 to the high-capacity 15.00 mm CM1500—optimized for your specific telecommunication, automotive, or interconnect requirements.
CM Series Coaxial Cable Selection & Engineering Guidelines
When integrating high-frequency coaxial lines into communication terminals, automotive modules, or base station runs, balancing physical dimensions, environmental protection, and bending tolerances is essential:
Matching Cable OD with Routing Envelopes
The outer diameter (Jacket OD) of the CM Series is engineered to match standard metric interfaces, ranging from 2.79 mm for CM280 up to 15.00 mm for CM1500. For small-space, highly flexible automotive links, the thin profile of CM280 allows for tight-radius routing, while larger models like CM1200 and CM1500 provide lower attenuation for long-distance base station connections.
Managing Mechanical Bending Limits
Bending a coaxial cable during routing puts stress on its physical components. It is critical to adhere to the specified static and dynamic bending limits. For example, CM280 supports an exceptionally tight static bend radius of 6.4 mm, while our high-capacity CM1500 requires a minimum static bend radius of 75 mm (and dynamic radius of 150 mm) to prevent internal dielectric damage.
Overcoming Critical Environmental & RF Challenges
Communication equipment and automotive setups face strict electrical and environmental constraints. We optimize our CM Series to resolve common integration bottlenecks:
Mitigating UV Radiation & Weathering Degradation
Outdoor coaxial runs are subjected to continuous solar radiation, humidity, and wide temperature swings. Standard PVC jackets degrade under UV exposure, leading to cracking and moisture ingress. AO Microwave’s CM Series utilizes high-grade, UV-resistant Polyurethane (PUR) jackets. Rated to operate across a wide temperature range of -40°C to +85°C, PUR provides exceptional resistance to tearing, weathering, and abrasion in outdoor installations.
Minimizing Attenuation with Foam PE Dielectrics
Dielectric loss is a major cause of signal attenuation over long cables. Except for the micro-scale CM280, our CM Series utilizes highly efficient micro-cellular Foam PE dielectrics. By introducing microscopic air bubbles into the polyethylene matrix, we lower the dielectric constant and increase the propagation velocity up to 83% to 86%, ensuring maximum signal power reaches the antenna.
Target Applications & Operational Advantages
By providing low insertion loss, high shielding, and excellent weathering resistance, our CM Series communication cables secure critical RF links:
Base Station Antenna Connections
