This is one of those brilliantly simple, yet elegant ideas that is
likely to gain wide adoptance:

"The antenna is made of a flexible, high-strength plastic lined with
conductive mesh inside a large (six- or eight-foot) sphere
constructed of a material similar to that used for racing sails. A
valve from a small compressor directs slightly more air pressure to
one side of the antenna, giving it a parabolic shape. At first,
Gierow and his business partner, William R. Clayton, worried that an
inflatable sphere might just blow away. But the GATR-Com's spherical
shape actually deflects air twice as efficiently as rigid disks do
and protects the internal antenna's shape from being distorted by
gusts."

"...With inquiries from a wide range of potential clients, Gierow
regularly puts in 70-hour workweeks in his warehouse office/lab. But
last summer he managed to take a week off to bring his family to the
beach. Not surprisingly, the antenna came too. "I was the nerd on the
beach with the really big ball," Gierow says, "and the T1 connection."
