    Just bought one and watched several videos by big ham radio channels, and this was the clearest and most concise demo I've seen. Everything I needed and nothing I didn't. Thanks!

    WOW! Great video! You explain things in easy-to-understand simple terms, and not in Klingon.

    Thank you very much! I have seen several RUclips videos, but nothing has been as clear and concise are your presentation. I’m going to be using it for my home-brew HF ham antennas.

    I just got my own NanoVNA and trying to learn how to use it. Very straightforward. Thank you for this video.

    Perfect introductory video. Didn't assume any prior knowledge, but at the same time without talking to me like I'm a spongecake. Thank you!
    PS - Did you know about connecting the two ports together for the "through" calibration? Hope this helps.

    During your calibration I observed at marker 3:48 in your video that you directly pressed the Calibrate button after the CAL button. Between those two the RESET button has to be pressed to empty old calibration data.
    For a 1 port calibration you may skip the Isolation- and Thru button.
    After you removed the CAL load from CH0 I saw a swr value of 1.37 at the cursor. Where was that value coming from? Because with an Open (or nothing connected) at CH0 this value should be very high (infinite theoretically). So the yellow trace had to be on top of the display. I hope this helps.

    Wow you saved me with your "shiny for short" I was confusing the load with it and I couldn't make it work

    Fantastic video and well thought out. I got a Nano VNA for Xmas, but now confused as to how I delete stored data that I no longer want...thanks.

    Very nice, I'm wondering can this test be performed through an LMR 400 coax cable with an LNA & BPF connected, no antenna. Would that still provide an accurate SWR or would I need to add in a 50 Ohm terminator on the input end of the LNA (from the antenna)? Or should this test get performed with the LNA assembly connected to the antenna? This is for a Radio Astronomy telescope project.

    How do you know which SWR reading is good or bad for the frequency range you choose to save? I can only assume you are connecting the Nano to the wire that connects directly to your antenna outside with no other equipment attached to get it's SWR?

    Hello!
    It's my question that how we can test an antenna for a bipolar monopulse uwb signal for example if that signal has a 5ns width and 100khz repetition..What is the frequency that I have to use as start and stop on nanovna to measure my antenna parameters?????

    Think you should have calibrated the thru as well by connecting the two ports together for a better reading. I had to at least 😉
