BNC's for up to 50 Mhz ............ONLY

All of mine went into the bin .

Maury Microwave sell a couple of VNA calibration kits with BNC connectors 

* 50 ohm 10 GHz - model 8550CK10
* 75 ohm 12 GHz - model 8580CK10

The only problems I have experienced with BNCs has been when they are incorrectly fitted - which is often the case. But I have seen this problem on SMAs, Ns and BNCs.

There are some crappy connectors around. I have a piece of leaky feeder made by Gore. It was for use on aircraft and cost a small fortune. Gore stuck some really poor connectors on them. 

I am not too impressed with Gore stuff, although Pasternack are the worst of the expensive manufacturers.
