The SLL-400-FPG coaxial cable, 2 pcs × 40 m, equipped with N-type male ↔ N-type male connectors, is a professional solution for telecommunications, antenna, and RF systems where low signal loss, stable electrical characteristics, and long-term reliability are required. The cable is designed for efficient data transmission at frequencies up to 6 GHz and above, featuring multi-layer shielding and a UV-resistant PVC outer jacket, making it suitable for both indoor and outdoor installations.
🫡 We are a team of veterans
We are a team of veterans with hands-on experience operating communication systems in real field and stationary conditions. SLL-400-FPG class cables are used in applications where instability, random signal losses, or long-term parameter degradation are unacceptable. We select solutions that demonstrate predictable and repeatable performance over long cable runs and in harsh environments.

💬 Comment / comments
A 40-meter length is optimal for fixed antenna installations, base stations, repeaters, and remote connection points where a balance between cable length and acceptable signal loss is required. The SLL-400-FPG cable offers stable electrical parameters, excellent shielding performance, and strong mechanical durability. Hermetically sealed N-type connectors ensure reliable contact and reduce the risk of degradation during outdoor installation. Other connector types can be provided on request.
