I have one of the original type NanoVNA. The connectors are on the end, not the side. Anyway, I upgraded the firmware several months ago to the 0.8 version. Ever since then the SWR measurements always read high. For example, I am getting a measurement of 4:1 on a vertical antenna in VHF range, but my Bird meter shows a 2:1 for the same antenna. I have tried calibrating multiple times. Any ideas?
