About This Assembly

RFC400 Cable

RFC-400 is a cost-effective 0.400" 50-ohm low-loss coaxial cable serving as a value-oriented alternative to LMR-400. It delivers strong performance on runs from 50 to 200 feet and is popular for cellular repeater trunk cables, outdoor antenna feedlines, and budget-conscious infrastructure deployments.

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 SMA cable assembly is well suited for cost-effective long antenna runs, cellular repeater trunk cables, and outdoor feedlines. The combination of reliable 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.

Frequently Asked Questions

What is RFC400 coaxial cable used for?

RFC-400 is a cost-effective 0.400" 50-ohm low-loss coaxial cable serving as a value-oriented alternative to LMR-400. It delivers strong performance on runs from 50 to 200 feet and is popular for cellular repeater trunk cables, outdoor antenna feedlines, and budget-conscious infrastructure deployments.

What is the signal loss of RFC400?

At 1800 MHz, RFC400 has approximately 6.8 dB of loss per 100 ft (0.068 dB/ft).

What frequency range does this assembly support?

This assembly is rated DC – 6 GHz, limited by the lowest-rated component across the cable and connectors.
