Review on 📻 LJJDSLYU HAM HF Band1-30Mhz Shortwave Radio Balun Unun DIY Kit: Excellent Performance with NXO-100 Magnetic Balance by Marcus Loeffler

The supplier emailed me a PDF with pretty clear instructions. It included winding instructions for 1:1, 4:1, and 9:1 configurations, so this works well for many setups. With some rubber washers or So239 connector and port sealant this should be waterproof but they are not included. I'm going to add an eyebolt at the top so I can hang and operate the antenna isolators. All in all, this is a great start for building a project with modality to get what you want.
