RP-SMA Female to Stripping Head Cable 50cm RG1.13

RP-SMA stands for Reverse Polarity SMA. In this connector standard, the gender of the inner conductor and outer sleeve is swapped compared to a standard SMA. Specifically, the RP-SMA male has a hollow center pin (female-style center) inside a male-threaded barrel, while the RP-SMA female has a solid center pin (male-style center) inside a female-threaded barrel. This design is commonly used on consumer Wi-Fi equipment to prevent users from attaching non-compliant, high-gain antennas that might violate regulatory limits.

The stripping head end is a prepared length of coaxial cable with the outer jacket and shield stripped back, exposing the dielectric and center conductor. To use it, you typically solder the exposed center conductor to your target pad on a PCB or antenna element. The exposed braided shield should then be soldered to the corresponding ground plane or pad. Ensure a clean, short solder joint to maintain the cable's 50-ohm impedance and avoid short circuits between the center pin and shield.

Yes, RG1.13 coaxial cable is generally suitable for frequencies up to several GHz, including the 5.8GHz band used for FPV video transmission. However, cable loss increases with frequency and length. For a 50cm run at 5.8GHz, you will experience some signal attenuation. For critical, long-range FPV links, a lower-loss cable type like RG316 might be preferable, but this RG1.13 cable is perfectly adequate for most short to medium-range builds and internal routing within a drone or ground station.
