1.8M EME Dish Project

This is all there is to the dish and just some 12.5mm wire mesh for the reflector.

The Ribs are 15mm square tube.

I made a template up in wood first then formed them to shape by hand. I used a large mallet, holding the rib between two large wooden blocks and slowly formed the required shape. Surely someone else can come up with an easier method!

Here is an Excel sheet i made for calculating the shape of the dish ribs, i used it to create a template in wood when forming the rib shape with a hammer. It may not be 100% correct so watch out but seemed to work ok for me!!
