Meh, this 1:9 #unun is not working properly or the connected 450 ohm load has a significant inductance that messes up the measurement 🤔
Also discovered that a #NanoVNA-H can malfunction when its battery is completely discharged, it only booted up again after disconnecting and reconnecting the battery... #hamradio #vectornetworkanalyser

Denke den Balun habe ich ganz ordentlich und sauber aufgebaut.
Jetzt braucht es noch Werkzeug damit die PL-Buchse eingebaut werden kann

Going with a Speaker Wire #randomlengthwireantenna with 9:1 #unun. Had so much fun with the #putikeeg mini #straightkey yesterday, putting in back in action for today's

I'm not attaching more coax, basically my random wire attaches using a pl259. It's a weird setup. I'd be willing to pay fairly for an unun like that. I could cut off the pl259 I guess, but I don't want to.

152 followers · 1491 posts · Server mas.toMade a 1:64 #unun to adapt small telescopic antennas to 50 ohm receivers. Seems to work quite well, unfortunately this AR8000 does not perform really well on #shortwave. But the #antenna functions 🙂
