This pigtail is the go-to solution for engineers deploying RF links in tight enclosures:
IoT & Telemetry Devices: Connects 2.4GHz/5.8GHz Wi-Fi/LoRa antennas to embedded modules in smart sensors and gateways.
UAV & Drone Systems: Enables compact antenna routing from flight controllers to external GPS/RF modules without strain on solder joints.
Test & Measurement Equipment: Used in benchtop RF testers, spectrum analyzers, and signal generators for quick, repeatable connections.
Wireless Access Points: Links internal PCB antennas to external SMA-mounted APs in industrial routers and mesh nodes.
Industrial Automation: Supports wireless HMI, RFID readers, and remote control systems where vibration and space are constraints.
Educational & Prototyping Labs: Ideal for rapid RF circuit development due to its plug-and-play design and low cost.
The 90° elbow design reduces cable stress by 60% compared to straight configurations, extending service life in high-vibration environments.
Precision 50Ω Impedance Match: Eliminates reflections and VSWR spikes — critical for digital modulation schemes like QPSK and OFDM.
Gold-Plated Contacts: Ensures low contact resistance (<3 mΩ) and corrosion resistance in humid or industrial settings.
RG174 Flexibility: 25mm bend radius allows routing around corners in dense PCB layouts — impossible with rigid RG58 or semi-rigid cables.
Snap-Fit SMB Interface: Enables tool-free, rapid mating — ideal for field service and high-volume assembly lines.
No Adapter Required: Direct SMB-to-SMA connection avoids signal degradation from additional connectors.
100% RF Tested: Each unit verified with VNA for S11 and S21 performance before shipping.
