Specs Summary
RG405_BLUE Cable
RG-405 Blue is the color-coded variant of RG-405, offering the same 0.086" semi-rigid construction with a blue outer jacket for easy identification. Used in dense microwave assemblies and lab environments where distinguishing individual cables at a glance is critical to efficient operation.
N Connector
Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor applications.
SMA Connector
SMA (SubMiniature version A) is the most widely used RF connector in the industry, offering a threaded interface that provides a secure, low-reflection connection from DC to 18 GHz. Its compact size, 50-ohm impedance, and broad frequency range make it the default choice for WiFi equipment, software-defined radios, cellular antennas, GPS receivers, and RF test instruments.
Common Applications
This N and SMA cable assembly is well suited for color-identified compact lab and microwave assemblies. The combination of reliable N and SMA connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.
