About This Assembly
Specs Summary
RG402_BLUE Cable
RG-402 Blue is identical in electrical specification to standard RG-402 but features a blue outer jacket for easy visual identification in multi-cable lab setups. Color coding simplifies cable management on test benches and helps prevent mix-ups in complex wiring harnesses or rack-mounted equipment.
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-coded lab setups and test bench cable management. 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.
