Principals of design of geodesic radio dish

Admin January 14, 2026 2 Comments

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…

Does a geodesic dome naturally form a parabola? (Relevant to design of geodesic parabolic radio astronomy dish)

Admin January 14, 2026 No Comments

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…

Radio observation in hydrogen line (1420MHz)

One design for making parabolic radio astronomy dishes is to use a geodesic design – how do amateurs make a parabolic dish using this?

Admin January 14, 2026 No Comments

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…

If I want to make full scale Ewan hydrogen horn what dimensions should I use for all pieces of wood that form struts?

Admin January 14, 2026 No Comments

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…
