Curt K7ZOO All Messages By This Member #28162 Hi All, This afternoon I was succesfully using my NanoVNA H4 with NanoVNA Saver -- no problems.

I have a few antenna analyzers, but the NanoVNA is my only VNA and I need to make measurements of choking impedance this week. Thanks for helping me keep ON schedule! de K7ZOO
