Nice! Good discovery :)

Clarence could you please share a link to the web page where you made the purchase? Thank you.

What was your wire spacing to yield 312 + j286 ohms? There should not be a large reactive component. Using 4NEC2, I modeled a 40-meter folded dipole at 50-feet off soil surface (moderate soil) using

Today I finally got a response from the seller to my follow up message asking if he could post some pictures of the PCB showing the v3.4 label on it, as it would be beneficial to his sales as well.

I just flashed the 800 mhz aa version to my NanoVNA. Works great, but no Config button. Is there a version out there that contains that in the Antenna Analyzer variant?

I need a holiday haha. Thanks for confirming my brain is kinda working.... Thanks for the help

A recheck of the EBAY Listing indicates he has 0 units left.. Want to bet he returns with changes in the listing

The case hides the battery size. I have a pre-3.4 and I upgraded to 1.5Ghz.. THe spec is showing a 400mah battery .. Not 3.4.. I find that 9-5 US time, +/-2 hours he's in the USA in his office.. When

Using NanoVNA SAVER, I calibrate and Sweep using 144Mhz Start 148Mhz end.. and you can set sweep x4.. that's 101 points per MHZ.. It takes a but longer.. The display does look real pretty and if you

I find that a cotton-tipped swab makes a nice stylus for the nano-VNA touch screen. Dana K8YUM

I didn't finish the impedance: The RF Z of the R+jX would be about 420 Ohms. -- Chuck, W5USJ

Soaring Spitfire, I doubt that your resistors would measure 200 Ohms at 2 meters? At DC the resistance will look OK. With any length of leads and some distributed capacitance the resistors will look

Hi Kayak, Since you're new to this, please go through the forum's WIKI and FILES areas. All your questions have answers there... The links are at the bottom of every email sent out by the forum but if

You brain must be really overloaded if you need confirmation about this! So I'll help you, yes, you are right. But I've seen at least two websites about experiments with optimal resistor topology for

Yes Kevin - you are on the right way. 1/ (1/200 + 1/200 +1/200 + 1/200) = 50

hi all, new to this. I have a question. are there larger screen nanovna and with the exact same hardware and reliability etc? if so, can someone post a link? thanks

One last one.... My brain has been overloaded lately so just wanted to confirm. If I use 4 parallel resistors for better accuracy as mentioned earlier, 4, 200 ohms will make it 50 ohms correct.

Yes. I too have found out that balun is necessary when measuring antennas.

While you are looking at TEK info, take a look at their vna tutor and support info. Excellent. Alan

I'd say the original poster's question regarding whether the item he was considering purchasing is a NanoVNA-H v3.4 has been answered, and the eBay seller complaints have gotten off-topic. IMHO,
