Hi. Is there any representative of miniVNA in Brazil? I would like to buy miniVNA Tiny, but I could not find where here. Also, is possible to use miniVNA as spectrum analyzer? Main usage is for antenna tuning and filter tuning.

plz i wanna know how to use mini vna tiny as asignal generator?

Anyone got an Extender they want to part with?

A short review of antenna and network analyzers:

I have a SARK 100, with the internal battery pack, ( i have fitted this ) , I have an issue , the swr readings are close , however the ohms readings are not , .
we compared 3 analyzers, mini 60, mfj 239( I think ) and the sark 100.
the swr readings were all within cooey (close) , as were the ohms , expect the sark100, where the others showed 50ohms , the sark showed 6ohms,
does anyone have an explanation and a fix please


I wish to buy minivna pro for testing EMI/EMC filters, and passive components.Can anyone please tell me the difference bet. minivna pro,minivna tiny and minivna pro BT and which is the right product for our application?
