Loads are widely available.? Check ebay for example.? But why do you need an accurate load?? 51 Ohms represents an SWR of 1.02.? And how are you measuring it?

The 50 OHM load (SMA-Male) that came with my nanoVNA-H4 measures 51.13+ ohms.? Not a good start for calibration.? Where is a good source for GOOD loads that are accurate?
