About This Assembly
Specs Summary
RG402_BLUE Cable
RG-402 Blue is identical in electrical specification to standard RG-402 but features a blue outer jacket for easy visual identification in multi-cable lab setups. Color coding simplifies cable management on test benches and helps prevent mix-ups in complex wiring harnesses or rack-mounted equipment.
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.
UHF Connector
The UHF connector (also known as PL-259 male / SO-239 female) is a large, low-cost RF connector designed in the 1930s for HF and VHF frequencies. Despite its name, its practical usable range is below 300 MHz due to its non-constant impedance design. It remains extremely popular in amateur radio (HF through VHF), CB radio, and marine radio applications.
Common Applications
This SMA and UHF cable assembly is well suited for color-coded lab setups and test bench cable management. The combination of reliable SMA and UHF 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_BLUE coaxial cable used for?
RG-402 Blue is identical in electrical specification to standard RG-402 but features a blue outer jacket for easy visual identification in multi-cable lab setups. Color coding simplifies cable management on test benches and helps prevent mix-ups in complex wiring harnesses or rack-mounted equipment.
What is the signal loss of RG402_BLUE?
At 1800 MHz, RG402_BLUE 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 – 300 MHz, limited by the lowest-rated component across the cable and connectors.
What is a 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.
