About This Assembly
Specs Summary
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.
F Connector
The F connector is a low-cost threaded coaxial connector used almost exclusively in cable TV, satellite, and over-the-air broadcast applications. It uses the center conductor of RG-6 or RG-59 cable as the pin, which simplifies termination and reduces cost. F connectors are found on cable modems, satellite receivers, TV tuners, and distribution amplifiers.
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 F and SMA cable assembly is well suited for internal WiFi and cellular module antenna connections in laptops and tablets. The combination of reliable F 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 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 – 2 GHz, limited by the lowest-rated component across the cable and connectors.
What is a F connector?
The F connector is a low-cost threaded coaxial connector used almost exclusively in cable TV, satellite, and over-the-air broadcast applications. It uses the center conductor of RG-6 or RG-59 cable as the pin, which simplifies termination and reduces cost. F connectors are found on cable modems, satellite receivers, TV tuners, and distribution amplifiers.
