OK1KIR EME Team - Antennas, Dish extension

From June 1 till June 23 continued hard work on extending the existing 4.5m solid dish (f/D= 0.42) to 6.1m (f/D=0.31) by zinc-coated mesh (pitch 6.3 x 6.3mm, wire 0.6mm). The mesh was formed and mounted to the Al supporting structure from 24 ribs by loops made from thin stainless wire. The ribs structure was strengthened by intermediate and outer circles.
