Specs Summary
RFC400 ULTRA FLEX Cable
RFC-400-UltraFlex combines the low-loss performance of 0.400" coax with the flexibility needed for complex routing, offering an economical option for installations that benefit from increased bendability. Suitable for rooftop antenna runs, equipment room patch cables, and mobile installs where budget and flexibility are both priorities.
BNC Connector
BNC (Bayonet Neill–Concelman) is a quick-connect RF connector featuring a bayonet locking mechanism for fast mating and unmating, rated from DC to 4 GHz. Its ease of use makes it standard in test and measurement equipment, video distribution, two-way radio accessories, and laboratory bench setups where cables are frequently connected and disconnected.
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 BNC and SMA cable assembly is well suited for flexible outdoor antenna runs and budget-conscious mobile installations. The combination of reliable BNC 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.
