Sarantel's powerhelix antennae (jpg)

A revolutionary mobile phone antenna has been developed by UK company Sarantel, based on the company's patented PowerHelix™ technology. When other conductors or the user’s hand or head are next to the antenna, performance is completely unaffected, unlike conventional antennas. The unique manufacturing process uses a special purpose machine from Finnish company Citam Assembly Automatics Oy, fitted with Renishaw linear encoders to give very high accuracy.
