#102: The Complete "Demystification" of the "VNA Measurements" Kind - Farewell Hello, Well, we arrived at last at The End of a rather long Road. The VNA gives to The Common User the Value: (g - o)*(l

Dave is correct. The SWR looks great, but a nice (short leaded) 50 ohm resistor would also look good. There's a commercial wire (HF) antenna out there that uses a big 'ole 50 ohm resistor at the feed

Certainly, the SWR looks excellent. Now, does it radiate? Dave - W?LEV -- *Dave - W?LEV* *Just Let Darwin Work* *Just Think*

Hi, I build a Bi-Quad Antenna for 430 MHz, measurements are on the photo, my question is this a useable antenna or is there something wrong? Thanks in advance. Regards ersoez

Teflon also handles a good bit more heat. In case you plan to solder it to something.

However, do not forget the time base accuracy is 0.5 ppm. Alan

Would one of these inexpensive devices solve your problem? I bought one (just in case) but haven't needed to use it. https://www.ebay.com/p/4024997830

I see in the review in the Jan/Feb 2020 QEX that the minimum resolution is 1 kHz and scanning a crystal might give a close approximation of its resonant frequency but not much else. I used nanoVNA

Hello Ed SDR-Kits has both SMA and BNC calibration kits which is documented. Soon there will also be 5 parts N calibration kit The 4 parts BNC and N kit is universal as being both male and female.

#100: Any 2-port Introduces Relations of Moebius Transformation Between g an G Hello, Allow us, please, to present these two ways, g is a Moebius Transformation of G, and G is a Moebius Transformation

I'm a newbie and my only experience with VNAs is borrowing a friend's AIM 4170 from time to time for antenna measurements. I recently purchased a NanoVNA-H and am waiting for it to arrive. I was

@Erik, PD0EK - 2 January 2020 - /g/nanovna-users/message/9053 Dear Erik, Thank you very much for the attached paper. Yes, indeed, we found and took a look at it some months ago.

DISCLAIMER - I have no pecuniary interest in Gigaparts or Gigaparts.com Actually I ordered a NanoVNA from Gigaparts... (claim of consistency and quality versus china direct) Received it in 2 days...
