  2. 2. A Dish Named Venus Quality Made in Indonesia The manufacturing of Venus dishes, a brand of Indonesian com- pany PT Subur Semesta, was the focus of a report in TELE-satellite issue 03/2008. But how well would those dishes perform in the real world? That’s what we wanted to find out first-hand in Europe, and PT Subur Semesta was kind enough to forward a 1.8 m segmented dish to us by airfreight. To make sure the dish arrives the robustness of the segments in perfectly sound condition struck us right way.

  4. 4. Anything missing? The LNB! The assembled dish mounted on the supplied stand Expert opinion Which LNB? PT Subur Semesta supplies its antenna with an important shortening ring. That way you can easily exchange the C + band LNB for a standard Ku band LNB. Very strong segments increase confidence in the antenna’s resistance to deformation. By using Galvalume alloy the dish ensures a long durabi- lity. The dish is supplied with all components and can be mounted very fast.
