Review on Matching Transformer Ancable 3 Pack Plated by Shane Palma

I bought them to experiment, so I'm not leaving a "bad" review, but will describe what I found for other potential buyers. The outer "shell" is just a thin piece of shrink-wrapped plastic. Inside is a two-piece plastic case that is easy to disassemble. So I wouldn't use it outside like that, it doesn't look very weatherproof. However, they are perfect for my experiment, rewinding the toroid for different impedances, and when I want to use it outside with a custom antenna, it's repackaged and covered in silicone.
