Description
The SMA Male Straight Crimp Connector for RG178 is a sub-miniature RF interface designed for high-density applications where a secure, permanent cable attachment is required. Because RG178 is a very small-diameter flexible cable, this connector utilizes a hex-crimp termination method. This involves sliding a ferrule over the cable’s braided shield and using a specialized crimping tool to create a 360-degree mechanical bond, ensuring maximum pull-strength and electrical grounding.
Constructed with a gold-plated brass body and a Teflon (PTFE) insulator, this connector maintains a strict 50 Ohm impedance and superior signal integrity from DC up to 18 GHz (depending on the specific grade). The threaded coupling mechanism provides a secure, low-loss connection with all standard SMA female jacks, making it a staple in WiFi antennas, FPV drones, and laboratory test equipment.
Key Technical Advantages
-
High-Strength Crimp Termination: The hex-crimp ferrule provides a rugged, permanent attachment that resists physical strain and vibration.
-
Superior Signal Integrity: Precision-machined to ensure a consistent 50 Ohm match, minimizing VSWR and insertion loss in high-frequency paths.
-
Enhanced EMI/RFI Shielding: The 360-degree crimp provides excellent shielding effectiveness (typically = -90 dB), preventing signal leakage.
-
Corrosion Resistance: The high-purity gold plating protects the connector from oxidation and ensures reliable conductivity over its long operational life.
