I thought I understood #antennas, until I actually measured one.

A simple LoRa experiment turned into a deep dive on why antennas, placement, and environment matter more than labels. Real surprises learning with #NanoVNA

A SeeSii nano vector network analyzer with two antennas attached in front of a Lilygo T-Echo meshtastic radio turned off.

The screen of the nano VNA with the analysis results.

Hooked up the Meshology 868MHz whip antenna to a #nanoVNA and got the following results.

SWR 1.247
LOGMAG -19.12 dB
SMITH 50 Ω

Will be using this on my Lilygo T-Echo at 98.8% power acceptance nearly perfect.

In der heutigen Übung im Modul #ElektromagnetischeVerträglichkeit ging es um Antennen, Dipole, Monopole und Schleifenantennen, deren Stromverteilung und Strahlungswiderstände, die wir in #CONCEPTII simuliert und auch mit einem #nanoVNA #Netzwerksimulator gemessen haben: www.twitch.tv/mathiasmagdo...

Photo of NanoVNA-H4 test setup for the JH-131 hybrid. Measured insertion loss, A-B isolation, and A-B degree difference (they should be ~90 degrees apart from each other). All measurement were reasonable (device appears good and will be put into lab stock for future use).

Photo of NanoVNA-H4 test setup for the DC-Block / High Pass Filter showing connections to VNA between source and measure ports. Part has IN and OUT ports marked. That's interesting (don't normally see that on a DC block or even a low pass filter... Interesting!

Photo showing NanoVNA-H4 performing "S21 Filter" measurement on the DC-Block / High Pass Filter. Use this primarily for GPS antenna DC isolation when hooking up multiple GPS receivers to a common antenna. It is working as expected...

Getting caught up with RF module tests to ensure they’re working properly. First up: Anzac (MA/COM) JH-131 90 deg hybrid. First time measuring phase with the NanoVNA-H4. TLDR: Both hybrid and NanoVNA appear to be working correctly. Next: A weird part number […]

I have had the #NanoVNA for a while to play with #NMR Tuning and matching, but I never connected it to the computer. Yesterday, I finally did it, using my Apple Macbook and the software NanoVNASaver: volpefirm.com/apps. It's very useful!

Taking a page out of @lgr-yt.bsky.social 's playbook, "This #nanovna doesn't have wood grain, now it has"

I don't suppose any #amateurradio or #sdr guys/gals has a schematic for a #nanoVNA v2.
I need to know the value of an 0402 decoupling cap on channel 0.
I replaced it with an 0805 10μF for now, like the cap on channel 1, but I'm sure it's a lower value.

Fixing an Unpleasant SD Card Slot Issue In a NanoVNA SD cards & the much smaller microSD cards are found on many devices, with the card often accessible from outside the enclosure. Unfortunately there’s a solid chance that especially small …read more
