Howdy - we have a project going on where we have several antennas inside a Blue 8” enclosure, and at least one of them is supposed to point through the acrylic end cap on the end without the penetrators.
The Al end cap would have been a non-starter for us, but we are having some antenna tuning issues due to the large Al mass in the o-ring flange rings, so my question: has anyone been successful either 3D printing the existing o-ring flange, or is there some other non-metallic option that is out there that folks have used (e.g. machined Delrin)
Thanks in advance for your help!!
