15cm RP-SMA Female to IPEX4 Cable RG0.81

Description

This RP-SMA female to IPEX4 connector cable is a critical RF interconnect for IoT and wireless communication projects. The RG0.81 coaxial construction maintains a consistent 50-ohm impedance over its 15cm length, minimizing VSWR and signal reflection to preserve link budget and data integrity. The reverse-polarity SMA connector mates with standard RP-SMA male antenna interfaces, while the miniature IPEX4 (often branded as U.FL) plug connects directly to the ultra-compact antenna pads found on embedded Wi-Fi, Bluetooth, cellular, and LoRa modules.

Designed for low-loss performance across sub-GHz to 5GHz frequency bands, this pigtail enables developers to route antenna signals away from noisy PCB environments, directly improving reception sensitivity and transmit efficiency. Its flexible cable and precise 11mm connector length allow for clean integration into enclosures, drones, trackers, and gateway devices where reliable wireless connectivity is paramount.
