As you can see from the pictures, it is a dipole placed in a dihedral reflector. The dihedral is made from sheet aluminum 350mm x 123mm. I left a flat on the edge of the dihedral for easy mounting on a support. This dish is also used to facilitate attachment of the "rigid coax" that supports the dipole.
The dipole is exactly 53.1 mm from end to end. It is made of enameled wire of 0.8 mm is 23mm ~ "background."
