Awesome. That is pretty much exactly what I was thinking of doing. My thought was that you could more easily weatherize something like this rather than a parabolic dish which has a lot of wind loading.

What filament did you use?

Conventional PLA. Since its the cheapest and surprisingly extremley stable for Ghz range RF applications

I recommed you to read the research paper "Measuring the Electrical Properties of 3D Printed Plastics in the W-Band "

(https://scholarworks.uark.edu/cgi/viewcontent.cgi?article=10...)

It was really useful for us when developing our lens with an FDM printer. Be warn that it does require an infill of 100% , so it will be quite heavy.
