+Measurements have been made with a NanoVNA-H (HW version 3.4) version 1.2.19 (Build time: Jan 31 2023 - 16:06:06)
+at 14.020 MHz (because that is around the frequency that I use mainly at my home QTH).
+
+## What cable to use?
+
+I usually use the H-155 at home because the 10m are a good fit from my
+terrace to the table in the living room and it has the least loss and
+weight is not a factor when deploying at home.
+
+For portable operation I use the RG-316 because it is very leightweight
+and is "not so lossy" than the RG-174.
+
+I'd take the RG-174 when I'm not sure about what lenght the antenna cable
+should be because I have two cables with 6m with the appropriate connectors
+already on the cables.
