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.

RP-TNC Connector

RP-TNC (Reverse Polarity TNC) uses the TNC threaded shell with reversed pin conventions, similar to RP-SMA. It is used on some commercial WiFi access points and outdoor CPE antennas, particularly in older Cisco and Linksys equipment, and offers better vibration resistance than RP-SMA in demanding outdoor environments.

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 RP-TNC and SMA cable assembly is well suited for flexible outdoor antenna runs and budget-conscious mobile installations. The combination of reliable RP-TNC 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.

Frequently Asked Questions

What is RFC400 ULTRA FLEX coaxial cable used for?

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.

What is the signal loss of RFC400 ULTRA FLEX?

At 1800 MHz, RFC400 ULTRA FLEX has approximately 7.2 dB of loss per 100 ft (0.072 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.

What is a RP-TNC connector?

RP-TNC (Reverse Polarity TNC) uses the TNC threaded shell with reversed pin conventions, similar to RP-SMA. It is used on some commercial WiFi access points and outdoor CPE antennas, particularly in older Cisco and Linksys equipment, and offers better vibration resistance than RP-SMA in demanding outdoor environments.
