Grandchild in front of Interkosmos-1 mock-up. The solar panels have been folded down to ease access to the mock-up. To show the flight configuration they should have been horizontal.

One view of the antenna on the back of a folded-up solar panel. Feed coax comes from below.

Another view of a PIFA where the feed coax can be seen through the mesh reaching the feed-point.

Detail of how coax reaches feed-point.
