Hi Paul,

if N is an alternative for you: N provides much better accurate quality for higher frequencies than BNC.

See pics:

The (slightly hot air bent) extended PE board permits hand isolation: Often a suitable balun for avoiding body ground errors is not needed.

Betreff: [nanovna-users] connector swap

hi all im thinking of changing from sma to bnc connectors on my vna,maybe mounted on an extender board hooked up to the vna with some small coax,is there any issues with doing this as regards acuracy etc,i assume using 50 ohm coax and re calibrating it should be ok?,any idea?.,cheers M3vuv.
