Introduction to Waveguides using the LiteVNA, Part2

This video shows my homemade slotted line and using it to validate the frequency extender shown in Part 1. The extender is also used to compare various fixed attenuators. 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.
