Conductive paint on a plastic cantenna without copper infusion in the plastic printing material: Short answer: usually no — conductive paint on a plastic cantenna is very unlikely to give…

Making tuneable length monopole to maximise cantenna waveguide function: As can be seen in photo below, I have purchased a threaded copper sleeve (sold as brass coupling nuts) and a…

Principle behind the design: Reversing the perspective: First and foremost, the conceptual approach is reversed. It is not that “the components of a geodesic structure form a natural parabola,” but…
A geodesic dome doesn’t actually form a parabola—but it very often looks like one, and that’s where the confusion comes from. Here’s what’s really going on. 1. What a geodesic…
Amateurs use geodesic techniques to approximate a true paraboloid with many small, flat facets arranged on a spherical/geodesic framework, then “pulled” into a parabolic shape. The approach is popular because…
A full-scale Ewen (often spelled Ewan) hydrogen horn is a big structure, and most of the confusion comes from the fact that the horn geometry is well defined, but the…
