Specs Summary
RG405_BLUE Cable
RG-405 Blue is the color-coded variant of RG-405, offering the same 0.086" semi-rigid construction with a blue outer jacket for easy identification. Used in dense microwave assemblies and lab environments where distinguishing individual cables at a glance is critical to efficient operation.
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.
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-SMA and SMA cable assembly is well suited for color-identified compact lab and microwave assemblies. The combination of reliable RP-SMA 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 RG405_BLUE coaxial cable used for?
RG-405 Blue is the color-coded variant of RG-405, offering the same 0.086" semi-rigid construction with a blue outer jacket for easy identification. Used in dense microwave assemblies and lab environments where distinguishing individual cables at a glance is critical to efficient operation.
What is the signal loss of RG405_BLUE?
At 1800 MHz, RG405_BLUE has approximately 25.5 dB of loss per 100 ft (0.255 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.
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.
