NanoVNA SAA-2N Overview 

At 14:10, when you start the calibration, it's a good idea to hit the RESET first. In some devices/firmware, this is a required step to clear the existing calibration. At 19:54, when you changed the stop frequency, notice that calibration indicator changed from C1 to c1, indicating that the current calibration condition doesn't match the current stimulus settings, and that the calibration is interpolating (not ideal).

Thank you everytime I get a better understanding VNA KQ4CD

The NanoVNA is such a useful piece of affordable test equipment. Thanks for the great review.

Very easy and explanatory description. Thank you for your nice presentation.

Ape, I just bought one of these today. Thanks for the in-depth video on this device. I am saving video for future use.

Just received my same exact unit today. Looking forward to building some VHF/UHF antennas with it.

Class is in session! Great info

👍😎 Thank you Professor Ape!♡

Well presented, and articulated information. Although I'm not as familiar with it's operation(s) as those who commented prior to me, your video will be an asset when I started getting acclimated to mine, which arrived today (11/9/2023) Thank you.

Very good review

Would you consider making a video about nanoVNA firmware updates? Or did you already do one that I missed? Keep up the great vids

Very good video. What you did not mention is, "How many sampling points can you set this model to do. My NanoVNA H4 came from the factory as only having 101 sampling points. Not near enough for me. After doing the firmware update, I was able to choose from 101 up to 401 sampling points. I let mine set at 401 sampling points 100% of the time. I wish they would allow up to 1000 sampling points. This amount is needed for checking antennas like a 160 meter off center fed antenna. Barry, KU3X

I just got one of these models. Would love to see a video on how to update the firmware.

Question: My antenna coaxes are terminated with either PL-259 or BNC connectors (portable). I''m leaning to this NanoVNA model because of the more robust "N" connectors (vs SMA). How does one calibrate with an "N" jumper and an N to SO-239 (or "N" to BNC) adapter? In order to calibrate with the extended plane in the right place, it seems to me that you'd need to use a PL-259 Short, Open and Load, rather than calibrating with the jumper and the provided "N" connector SOLs and then adding the adapter after calibration to connect the antenna? How do most people deal with this? Thanks! Great presentation!

thank you for your videos they are very helpful especially since I am very ignorant about NanoVNAs. Also in your accent I think I hear a bit of South Philly?

Hi, have a older Version S-A-A v2 with open Case, how to power Off the device. Disconnect the cable to the battery works but is not a fine solution.

I watch a lot of your videos and I have a question thats kinda off topic about this video. I make a lot of my own yagi's and QFH's (for receive only) and I sometimes use 75 ohm RG6 coax...the kind for cable tv. When I go through the standard calibration for calibrating the vna and set my start and stop freqs for checking the swr..am I getting a false reading with it having 75 ohm coax or is it not enough of a difference to notice? My swr's seem to be pretty good on my yagi's but Im not sure if its way off having the 75 ohm coax on them. Thanks for the videos

New to all this... On your recommendation, and others, bought a nanoVNA-SAA2N from Amazon. Needed an SWR meter; glad I bought the VNA instead. Tested a 300 ohm twin lead fed folded dipole/doublet with a 1:1 balun that I built for a President Richard... President's SWR yields 1.0 across the 11m band, but the VNA yields 1.5 over the same range. I do believe the VNA is properly calibrated... Wondering if I should try to improve the SWR as tested by the VNA..., can I trust the President? It is named after Dick Nixon, afterall... Also, tested SWR for a number of rubber ducks (mostly Baoeng), and 771 types, as well as two Nagoya NA320a. The rubber ducks are all pretty good in a narrow range around 2m and 70cm. The Nagoya NA771s are terrible on either band, but the Abbree NA771 are very good. Nagoya 320a are very bad... looking for an alternative triband... The 1.5m rubber duck antennas, though different, that came with my Baofeng BF-R3 and my BTech UV-5X3 are both great in that band.

As someone with zero VNAs, looking to make it one VNA, would you go SMA or N? Especially given that most antenna are SO/PL, you'll need adapters either way, thoughts? Thanks.

Hello Ape, I am a noob to all the VNA's. Will this unit perform all the functions that the H4 will do? Along with testing antennas and feed line I want to be able to check attenuators. What are the benefits of purchasing this unit over the H4? Tnx, NI6J

what kind of connector do we need to hookup Nano saa-2n to PL-259 connector male ,and what about the H-4 thanks 73

Hi, I'm looking for a pocket VNA which can support upto 7.2Ghz. Any recommendations? And also a spectrum analyzer.

If you were buying a VNA what would you recommend for brand and model?

Nice video but it is more of a tutorial. Do you recommend this model? How does it compare to other brands? Is it a good buy? What else should I consider? Thanks.

I passed all 3 Ham exams, and am now learning about ham radio by trying to use it. At the moment I just have a Baofeng HT and am only communicating and experimenting with that HT and antennas for VHF and UHF. Before long I will purchase an HF system and I will then be interested and experimenting with HF antennas. My Baofeng uses an SMA connector and my experimental UHF and VHF antennas use BNC connectors (so I go through an adapter). I see that the NanoVNA SAA-2N uses N type connectors. How much of a disadvantage is that. (I assume every connector I go through adds loss and distortion.) Should I just go with the regular NanoVNA that uses SMA connectors, or is there an advantage for stepping up to the V2 model even thought it will required another connector type? Is the connector type and adaptor loss a non issue?

These really are great tools. Good review Professor! I need to get me some of that N action.

Any recommendation for firmware version?

Curious if an update would increase the data points above 201, i believe the newer versions go to 401?? 73

Hi Ape this is david w4btt how do you do a antenna sweep if you have 49:1 unun in line

Just don't know what one to get in KQ4CD Paul

QUESTION. How does one read a Nano outside, next to impossible in my experience.

Could someone please do a video in Smith Charts and polar charts? I find them really hard to read.

You need to calibrate the open without a coax jumper.

I have a cheap version but she works! I think 😆

We use N-Type in the telecommunication industry

Thanks for sharing! 73 DG1GHR

Please someone tell this guy his START freq is lower than the LOW END of his DUT.

you dont speak, you wispere and I can not understand
