Description
Atlantic Radio RG400
M17/128 Double High Temperature Coaxial RF Cable (12.4GHz)
Professional-Grade Flexible Double Shielded Coax – Sold by the Foot
The Atlantic Radio RG400 is a high-performance, 50 Ohm coaxial cable engineered for mission-critical RF and microwave applications. As a certified M17/128 Double High Temperature coax, this cable is designed to maintain signal integrity in extreme environments where standard cables fail. It features a sophisticated double-shielded construction that provides superior EMI protection and minimizes signal attenuation, supporting reliable data and voice transmission at frequencies up to 12.4GHz.
Built for versatility, the RG400 utilizes a PTFE (Polytetrafluoroethylene) dielectric and a stranded center conductor, offering exceptional flexibility for routing through tight bulkheads, vehicle conduits, or complex rack systems. The outer tan FEP (Fluorinated Ethylene Propylene) jacket is not only abrasion-resistant but also chemically inert, allowing the cable to operate safely in temperatures reaching up to 200°C. This makes it the ideal choice for aerospace, military, and high-power commercial RF setups that require a durable, low-loss interconnect.
Whether you are building custom jumpers for repeaters, installing maritime antenna systems, or working on millimeter-wave projects, the Atlantic Radio RG400 provides the electrical stability and mechanical ruggedness required for professional-grade installations. Sold by the foot, this cable allows for precision customization, ensuring you have the exact length needed for your specific RF environment.
