LQ 900 Coaxial Cable

LQ 900 coaxial cable is a large-diameter coaxial cable designed for professional RF applications that require very low signal loss over long distances.

1.Impedance：50 Ohms
2.Cable Diameter: 0.870 inch(22.10 mm)
3.Outer Jacket Material: Polyethylene (PE)
4.Shielding: Dual-layer(Aluminum Foil & Tinned Copper Braid)
5.Propagation Velocity: 87%
5. Operating Temperature: -40℃ to +85℃

1.Very low Signal Loss: The large diameter and foam polyethylene (FPE) dielectric make LQ900 ideal for long-distance runs where maintaining signal strength is critical.
2.Environmental Durability: The standard black polyethylene(PE) jacket offers excellent resistance to UV light, moisture, and abrasion,suitable for outdoor use. The LQ 900 with jelly is ly designed for direct burial and is watertight.
3.Effective Shielding: The combination of aluminum foil and and a tinned copper braid offers excellent shielding effectiveness against electromagnetic interference, which is crucial for maintaining a clean signal in demanding RF environments.
4.Comparison with other LQ Cables: The LQ series follows a logical numbering system where the larger the number,the thicker the cable and the lower its signal loss(attenuation) over distance. LQ900 provides lower loss than LQ600,which in turn is superior to LQ400. This makes LQ900 the best choice for the the most demanding, long-distance links.

This cable is typically used in high-performance infrastructure such as cellular and microwave base station feeds, satellite communications ground systems, and broadcast antenna feeder lines where low loss is a priority.

*The attenuation is typical value, Maximum value shall be 105% of the nominal attenuation value.
