Today progress on the Prescott HERA dish took the form of building the dish hub and rim.  The hub is where all the dish supports (25′ pvc pipes) meet. The hub is made using concentric “sonotube” concrete forms in which are embedded 3″ plastic pipes set in a radial pattern.  Its basically a giant tinker toy hub made of cement. At the same time we also put up the rest of the rim support poles with their fixtures to receive the dish supports.
