Hi there
Question: What is the maximum impedance capable of being measured via a nano VNA?
Context: I am working on an impedance matching section (1/2 wave length of coax) for a folded dipole antenna (VHF 2m amateur radio band). How ever when I measure the impedance of the folded dipole it returns a value of approximately 25 Ohms, not the 300 Ohms expected.
Some further testing with Resistors shows the impedance value error seems to increase significantly around 150-200 Ohms. 200 Ohms (2x100Ohm resistors) results in a measured value of approximately 140 Ohms.
Has anyone else experienced this same issue or have some more information on this?
It is very possible my aerial construction is off but wanting to explore this, and haven't found a good source on maximum R,X specifications for the nanoVNA
