Review on Balun One Nine v2 Barebones: Affordable 9:1 HF Antenna Balun and Unun for Shortwave with Input Protection, Ideal for RTL-SDR, Ham It Up & SDRPlay by Maurice Strawther

As previously mentioned, this V2 product is incorrectly labeled and described. It seems the PCB designers (and advertisers) thought the primary/antenna coil was a tap center. It's not like UNUN does. Still, it's a well-constructed unit in a user-friendly form factor. If you need BALUN, please buy V1 unit. If you need UNUN, buy this one, V2. Nooelec, you need to do some research and correct the name and description of your item.
