If I wanted to buy a nanoVNA which one should I buy? I am a bit confused on who makes the one that will be best supported with updates and which one has the best hardware/firmware. What is a clone and what isn't a clone when it comes to open source programming. Thanks

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?????

Question: Why do you need the patch cord to calibrate? Why not just screw the calibrators directly into the VNA's SMA connectors? Aren't they SMA female?

I just want to know how to get the SWR using this. You started just fine, mentioning how most of us will be using this for the SWR only. Then you started to deviate, how the other settings and features are used stating it's for another video, but then you continued with your distractions. You lost me. I just want you to show how to calibrate this thing for starters, with the right and only one screen showing so we can now insert an antenna and get the readings? Geez, why is every video on this Nano makes you rant.s

@peterbuxton7415 Жыл бұрын
Thank you for clearly explaining the order of many details that aren't intuitive from the menus. However, I'm still confused by the way the traces are saved to Save 0 after the Calibration was saved there earlier, and you said the calibration should be resaved if some parameters are changed in the setup. It seems as though Save 0 is a multi-section memory that can save each parameter separately from another at different times depending on the most recent menu parameter before saving.

The primary purpose of a balun is to match a balanced load to an unbalanced transmission line. In order to accomplish this the balun must present a high common mode impedance. You have not investigated the choking impedance- so what I see you have is a transformer and perhaps a balun- but you will not know until you measure Zcm. It would also be interesting to know what the insertion loss is. Dale W4OP
@BusDriverRFI Жыл бұрын
If you want to look at common mode, you need to analyze the antenna feed point. In this experiment, the load is a not a non resonant load as there is no appreciable reactive component. But looking back from the load towards the transmitter, an X value will be divided by a factor of 4 and the current phase shift can be calculated from that at 50 ohms resistance. It will be roughly constant from 10m through 6m. Cancel (minimize) your antenna X values and common mode currents are minimized. This can be done by changing the antenna dimensions or cancelling the X values through some fixed reactance on the antenna.

@davewood4604 Жыл бұрын
Excellent, thanks for this. I use my NanoVNA a lot for antennas and radios. I am always a little frustrated by the setup process. I have now recalibrated and saved the setup so my display and calibration has a baseline when I switch it on. Meanwhile. I would love to see how to measure feeder length, then factor that into Antenna analysis. Basically I have 1 antenna very high on a mast, another antenna at the bottom of the garden. In particular the one at the bottom of the garden; its a bit tedious to go all the way down the garden for any testing.

Great explanation! I'm testing a 9:1 Noo Elec type small balun, and I was expecting to see similar results when measuring it with the Nano VNA from 50KHz to 25MHz. However, with a 470R resistor attached in place of the antenna, the Smith chart impedance readings are far from perfect. They are capacitive before 3MHz and inductive after, with the resistive component dropping. The readings are almost perfect with a 47R resistor though.

@IK8XOO--Paolo Жыл бұрын
It's not a test if you don't check your balun's output: A balun's main job is to match a balanced component with an unbalanced one in an antenna system to avoid common-mode current, a radiating coaxial cable, and distortions in the polar pattern of radiation. Furthermore, you have not checked the insertion losses: about that, how was the compound of the toroids chosen and how was the starting number of the coils calculated? Attention: the magnetic fluxes of those two toroids in that position tend to concatenate
