The Oyster® external unit weighs only about 11 kg. Despite the weight reduction, it is even more solid than its predecessors. Here, stability makes the difference. Not only in terms of the proverbial “longevity of the Oyster®”, but especially when it comes to uninterrupted reception. Manufacturers trying to cut corners run the risk of producing an unsta- ble antenna system that is susceptible to the wind. Image interferences are then inevitable.
The stability of the Oyster® is the result of cleverly applied engineering skills and state-of-the-art, high-quality materials like the ones used in motor sports. The single-piece dish arm is made of ultra-lightweight magnesium. And yet, it is extremely rugged and torsionally rigid.
The feed arm is made from glass-fibre-reinforced plastic, with carefully calculated internal webs providing ultimate torsional stiffness. In plain words: It won’t flex – ever. In addition, this meticulously crafted com- ponent provides the space needed for wiring, inclination sensor and compass. If fitted with the SKEW option, this part is also integrated in the feed arm for protection against the elements.
