SMA Pigtail Guide: RG174 vs RG316, Loss, Bends & Waterproofing
Should you pick RG174 or RG316 for lower coax attenuation and safer bends? If you’ve ever opened up a Wi-Fi router or handled an FPV drone, you’ve probably come across both RG174 extension cable and RG316 jumpers. On the surface, they look almost interchangeable: both are 50-ohm coax types, both sit in the 2.5–3 mm size range. Yet once you dig into their specs, the differences show why engineers tend to prefer one over the other in specific contexts.
