The issue is not the VNA, but rather? your lack of undertsanding as to how antennas perform/function.The way you have it set up, the outside of the coax shield and your VNA are part of the antenna

Several comments about buying the larger screen. However, all I can find are the 2.8" screen versions. Where/How can I find the larger version -- or, is the 2.8" screen the larger version?

Great thanks for you answers!! I think I understand things much better now. Yes, the radiating emlement is parallel to the ground plane in this setup for reducing space, but it can be changed to

Hi, I am facing similar in fact worst situation. Just using the same coaxial cable you showed in your picture and connecting to its end a 20 cm bare copper wire (that I am planning to use as an

With the antenna that close to the VNA, ferrites are a must at both ends of the connecting coax. Install ferrites and move the antenna structure several wavelengths away from the VNA. Also, for an

A better picture would help. Seems like your ground plane is tiny compared to the radiating part. And its hard to see but it looks like your ground plane is parallel to you radiating element. Both

Looks like your feedline is radiating and your USB connection becomes part of the antenna. Try using ferrites over the outside of the RF cable right at the antenna to decouple your cable.

Hi, I try to use NanaoVNA for measuring a vertical ground-plane antenna at 170MHz for later impedance matching. A picture of the test setup is attached. Connecting NanaoVNA to USB affects the

The known official store of Hugen is here https://www.alibaba.com/product-detail/Hugen-NanoVNA-H-New-item-Original_62342877955.html The other sellers on ebay, aliexpress, amazon, etc are usually

Agreed. So is there a seller on UK eBay or Amazon that you bought before and he wasn't selling fakes?

Owen cannot compare a $10k VNA against a $50 one I am happy with the cheap and cheerful H version for basic understanding and experimentation To expect lab grade performance is ridiculous John ve3ips

I second Don's question. Email?
