I’m not actually in the gain measurement, I just use the log formula. VA3AQB 🇨🇦 Alan

Actually it can if you connect a receiving antenna to port-2 (S21) with the antenna to measure on port-1 (S11) via a long piece of coax. Place the antennas far apart out in the open and rotate the ant

Don't expect more out of a VNA than it can deliver. It can help you design a good matching circuit at the feedpoint of the antenna. But it cannot help you measure the antenna's pattern or gain. 73, Ke

Good day to all the group. I have had my VNA fir a few years and really not done to much with it other then playing fir the first day or so. I had to build a antenna fir 915Mhz and I needed a little g

Designing the cases required several nights of hard work and design choices has been done in order to : - Accommodate a large enough battery and internal stylus fitting - Have no visible screws on the

Hi, I have build my version of the NanoVNA V2, in short it is in a hammond aluminium case with 4" Display and 4000 mAh battery. Currently selling some on tindie: https://www.tindie.com/products/blackm

Hello Fredmoore3 The enclosure construction with the addition of 2 M/M SMA connectors and 2 F/F bulkhead connectors is exactly what I was planning to do for my nanovna H4 All these additional connecto

Good afternoon Dean. I have been seeing all kinds of cases for the nanoVNA and just thought I would throw in what I found and basically what all nano cases, regardless the old originals like mine or t

Jason, As an ex-employee of M/A-COM I can vouch for what you learned. We made special connectors for the test equipment companies, HP, Wiltron and such. The plating should flake off any OS connector.

Using the SMA-M/SMA-F adapters as connector savers like I think you show, Stan, is a very good idea. Even very high quality SMA connectors (>$50 each) degrade in match very quickly. Cheap ones with on

Sounds like a perfect excuse to buy a 3D printer! 73 Ed N5KZW

... saving me the cost...

By the way. This case was an especially a good deal for me because it was just a short 20 min drive from the store for me to go pick it up,swing m the cost of shipping. I also picked up some cheap BNC

P.S. The tubing was placed back over the stylus and the the assembly was held in place while running the beads of hot glue. This provides for proper alignment and acts as a heatsink for the pieces of

The attachment for the stylus is two pieces of 3/8" heatshrink tubing I shank down around the stylus. The tubing can then be loosened for a good fit by rolling the stylus between two hard surfaces. Th

Very nice. The stylus holder is a great idea. Thanks for sharing. --- Ciao baby, catch you on the flip side 73 de W3AB/GEO http://www.w3ab.org You can say "over", you can say "out", you just can't say

I have a nanoVNA model H, and I've been several designs that were quite clever. I am looking for an enclosure that would fit the nanoVNA model H with the addition of chassis mount PL-239's to SMA's in
