Nice one,

I thought you are supposed to calibrate each specific frequency (range) test for better accuracy. Only one calibration for all frequency testing is much easier.

At 2:44 (the thru step) you connected both terminals of a single cable correct?

You calibrated the vna, then changed the freq range. The vna takes the calibrated range sample points, and extrapolates it to the new range. You might end up with only 1 or two points of sampling over the entire new range.

You must calibrate over the frequency that you going to use, not calibrate then choose the frequency range.

ok so when you calibrate the vna and save it to a channel do i have to re calibrate next time or can i go the the channel i saved it on and check a diffrent antenna without re calibrating ?

Здравствуйте ! Вы не подскажите как настроить что бы при прокрутке можно было встать точно на нужную частоту, а то у меня перепрыгивает мне надо 145.300, а курсор или 142.800 и следующий сразу 146.600

Did you use JUST 1 patch cable and connect to BOTH ports, OR, 2 separate cables that were supplied? Having to receive this device without a manual, how to setup, how to calibrate this seemingly simple device in disguise is frustrating especially if you have a different version like the H4, with a different screen. Geez. To be honest, I'm goings around in circles just to get the SWR ONLY.

You kinda goofed it. I suggest you watch a few nanovna YouTube videos as to why.
