About This Assembly
Specs Summary
RG402 Cable
RG-402 (UT-141) is a 0.141" semi-rigid coaxial cable with a solid copper outer conductor that holds its shape once formed. Its low loss and excellent phase stability make it the standard interconnect in microwave test setups, network analyzers, and laboratory bench assemblies. Ideal wherever cable position is fixed and mechanical rigidity is advantageous.
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 microwave test bench assemblies, network analyzer connections, and lab setups. 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 RG402 coaxial cable used for?
RG-402 (UT-141) is a 0.141" semi-rigid coaxial cable with a solid copper outer conductor that holds its shape once formed. Its low loss and excellent phase stability make it the standard interconnect in microwave test setups, network analyzers, and laboratory bench assemblies. Ideal wherever cable position is fixed and mechanical rigidity is advantageous.
What is the signal loss of RG402?
At 1800 MHz, RG402 has approximately 15.5 dB of loss per 100 ft (0.155 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 18 GHz, limited by the lowest-rated component across the cable and connectors.
