‘TIKALUNA’ GLENBURN, VICTORIA, AUSTRALIA
This article appeared first in DUBUS 2/2006 and provides full constructional detail including photos of the dual feed system. For many years the interaction and feed methods to illuminate dishes has always been a matter of conjecture. The 70 cm feed (dual polarity switching) is revisited in this article and provides the lowest practical loss system of this type. Tips and construction methods as well as set up procedures are covered in the paper.
