Review on 📻 HAM Equipment Balun Kit NXO-100 for 1-30Mhz Shortwave Radio: Magnetic Balance for Enhanced Performance of Amateur Radio Antennas - DIY by Seth Damain

I did not receive the promised email with instructions and if you are looking for vendor support it deserves zero stars for a broken promise. I found good information on YouTube. The kit was of good quality although some of the holes were misaligned. Easy to attach as the shell is soft. Your mileage may vary. There wasn't enough wire for the ten turns they mention, but YouTube made nine turns, which I did. The kit came together easily, although I had to use a piece of wire I had on hand for a connection. They really should have been a little more generous with the wire. Because they claim 1:9 is for people with an antenna tuner I can't use them for that. Maybe I would have gotten better results with a longer wire, I don't know. I'm limited in space for long cables and have used 18 meters. I tested on amateur HF tapes. If you have a good antenna tuner you can use it with a handy but compromised long wire antenna. See table.
