Hi guys
Wonder if you can acctually cut an exact 1/2 wave coax for a given freq without getting VF and math usong nano VNA. It woukd be very useful when making 4:1 balun with better accuracy rather than estimating with math.
I also need it for duplexer pigtails.
Ive been searching in youtube if soneone ever did a video.
Thanks more power
