Introduction to Waveguides using the LiteVNA, Part3

This video compares various 3D printed plastic horns by looking at their radiation patterns and VSWR. Also shown is a simple experiment where we attempt to compare a few different solid materials placed inside of a waveguide. EEVBLOG thread, Experimenting with waveguides using the LiteVNA It was mentioned that The Signal Path channel made a video on 3D printed waveguides. The attached link takes you to what I believe they were referring to. He made a few horns and a filter. He’s experimenting at much higher frequencies than I am and surface finish. During this video, I show a couple of printed horns from the following link. Maybe we can test them out in the future.
