Re: QCX mini: RF output BNC or SMA #poll-notice
Maybe something like these are a little better/sturdier:toggle quoted messageShow quoted text

Definitely SMA are not the best if you need many connect/disconnect cycles. They are not even nice to handle compared to BNC, let's admit it, size ok but why suffer?
They change characteristics based on the torque applied (yes, both ways, more or less torque do both affect the measure), I have a MiniVNA Pro and it is nasty when performing calibration, you just need the exact range of torque else the graph will be funny. Not nice.
I ended up using a SMA saver(m/f) on each connector to limit the wear (SMAs are a PITA to substitute on the MiniVNA),sadly it won't do much on the torque issue.

BNC connectors without the plastic housing exist. I have a mini oscilloscope, a DSO138, that has one.
