Specs Summary
About This Assembly
1.13 Cable
1.13mm coaxial cable is an ultra-miniature 50-ohm cable used primarily for internal RF wiring in compact wireless devices such as laptops, tablets, and embedded modules. Its extremely small 1.13mm outer diameter allows it to pass through tight spaces inside consumer electronics, connecting antennas to WiFi or cellular modules with minimal signal loss over short distances.
RP-SMA Connector
RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.
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.
Common Applications
This RP-SMA and RP-TNC cable assembly is well suited for internal WiFi and cellular module antenna connections in laptops and tablets. The combination of reliable RP-SMA and RP-TNC 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 1.13 coaxial cable used for?
1.13mm coaxial cable is an ultra-miniature 50-ohm cable used primarily for internal RF wiring in compact wireless devices such as laptops, tablets, and embedded modules. Its extremely small 1.13mm outer diameter allows it to pass through tight spaces inside consumer electronics, connecting antennas to WiFi or cellular modules with minimal signal loss over short distances.
What is the signal loss of 1.13?
At 1800 MHz, 1.13 has approximately 38 dB of loss per 100 ft (0.38 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-SMA connector?
RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.
