in this video, we take a look at the NanoVNA SAA-2N and how to adjust data or sweep points when analyzing an antenna.
Note: This NanoVNA was sent to me free of shared from AURSINC in exchange for this video review.

Thank you for the excellent video. Just a comment about the static discharge from the antenna for the benefit of the viewers. Note that the static build-up is actually a charge between the coax shield and center conductor of the antenna feedline stored on the dielectric insulation. In short, the coax is a storage capacitor. The antenna is the charging device, building up the voltage caused by dry air moving across the antenna elements. So a longer run of coax is a larger capacitor. I was once knocked across the room by the charge built up in a 100 foot run of RG-8 that was not connected to a radio but had been connected for a few days to my longwave radio antenna with its 2 miles of 22 gauge wire in it. I don't know what voltage it had built up to, but THAT voltage at THAT current threw an arc that knocked me down, and could and would easily kill any piece of ham equipment it was plugged into except possibly some old tube gear. Lesson learned. I now include a 2M Ohm resistor across all my coax runs at the antenna to dissipate any charge before it can build up.

That is the model VNA I have. I am about to check all my antennas after a long time of not using them. Luckily my antenna switch grounds all but the antenna I am using so that handles the arcing. And, when turned off, it also grounds all antennas. That is a nice bonus of the switch.

Thank you Dr. Ape! I bought one from Aursinc (Amazon purchase for convenience) I actually like the “N” connectors over SMA. I also bought the “Mini-1300” Antenna Analyzer from the same place. IF it’s working properly, it’s another excellent piece of test gear. I’m going to hit your library of videos in a sec.. looking for any Mini-1300 content. Thank you much for your focus on test equipment for the dumb-ass ham. aka = Me. 🤣

Fully functional and probably never left the bench or pristine environment. BUT… my wife and brother(he helped select it LOL) got this for me for Christmas and just assumed it was a spectrum analyzer. So it sits…. :)

Great video and many thanks! I'm glad I purchased this item and more so since I discovered your channel. You provide great advice and your explanations are always succinct. My question was with your marker for the ten meter band. Checking with the ARRL band chart, it appears that setting the marker at 28.850 places the marker out-of-band even thought the blue chart section reads for ten meters. Am I getting that wrong?
@TheSmokinApe
@TheSmokinApe 2 жыл бұрын
Hey Randy, the band is from 28 - 29.7 without my glasses on! But you make a very good point that the blue bars are not for IUT Region 2 where the US is located. You can configure them in the options and need to for 40m and 440m and maybe a few others if I recall correctly.

I bought one of these. I must say the reason I bought it was to tune my Buddie Stick Deluxe antennas. I have the stick deluxe and the pole deluxe. So my main reason is it's much smaller than my Comet analyzer and easier to carry. I figured it out but I think a video using the screen to program it would be good. For now, I am only using it to check my tuning and SWR. Could you do a video about how to use this in the field? Thanks again for the info. Keep up the great work. KO4PDI 73

@@TheSmokinApe Hi SmokinApe - Thanks for getting right back to me. I agree with what you say as it applies to the valleys in the scan. As an example of what I don't understand is shown at 10.77MHz. There is a red dot here (assumed point of calculation) with an SWR of ~ 7.9. I can't make out the dots on the blue trace but the result is ~4.1. Cheers! - Bill

Hi SmokinApe I have a question, I really want a nano VNA, this one seems to be the best of them all, even currant date. If you agree please let me know I want a VNA with the 4 inch or bigger screen and up to 3gig seems great even though I will never use it, you never know. It seems well built and I was hoping to get some advice. I live in Canada and can only find these big ones on Amazon, so i hope they are not fakes, then seem legit. I am a new ham and cannot afford a really antenna analyzer like rig expert, and even so nothing in this form factor even comes close like the Nana to doing both HF and uhf/vhf, that is also important to me. It seems the Nano Saa-2N is the way to go, it may not be as lab quality as the Rig Expert and others, but for Ham is it really necessary to be that high degree of accuracy. Please advise. Thanks love all your stuff.

Great video. Thanks for posting. I always knew how important sampling points are. The downfall of one of my antenna analyzers is it is limited to only 80 sampling points. To me, it's limited to single band coverage.......and it was an expensive analyzer. My SARK 110 can sweep up to 10,000 sampling points as a stand alone unit, but it takes 20 minutes for one sweep. I like my NanoVNA H4. I do not want to lug a computer around with me. The H4 can sweep up to 500 sampling points as a stand alone unit. What about the SAA-2N....how many sampling points as a stand alone unit? Barry, KU3X

Just a thought for "Ham Nuggets" discuss covert ways to use our equipment and communicate without everybody listening in. There are several ways discussed by KM4ACK. This video does a deeper dive. It's an interesting channel that discusses comms everyone now then. Security episode of interest. kzbin.info/www/bejne/l6GvqZiGo8yBoq8 I'd love to hear you and TO discuss how to speak privately and legally but listened to by few people. It's great for paintball. I'm going to set this up for some teens. It adds a tech element to the game. It's fun for old hams too. Lots of simple creative ways.
