Coaxial Antenna Cable RG402 50 cm
Professional coaxial antenna cable RG402, 50 cm long, from manufacturer: China. This cable is designed for transmitting high-frequency signals with minimal loss and guaranteed electrical stability. Thanks to its well-thought-out design and quality materials, it is ideal for use in drones and quadcopters, RF modules, portable and laboratory setups where precise signal transmission and resistance to temperature loads are required.
Key features of the RG402 50 cm model: multi-strand coaxial design, inner conductor made of silver-plated copper (SPC), high-quality PTFE (fluoroplastic) dielectric, and outer conductor made of SCCS (silver-plated copper-clad steel). The FEP extruded Teflon jacket provides high chemical and mechanical resistance and a wide operating temperature range from -55°C to +200°C. The nominal impedance of the cable is 50Ω, making it a universal solution for antenna circuits.
The cable has low linear capacitance — 95 pF/m, and a velocity factor of 1.43 ensures stable transmission with predictable time delays. This is especially important for systems where correct phase relationships and minimization of reflections are critical. The design and materials guarantee good electromagnetic compatibility and a long service life in harsh operating conditions.
