Make it a parabola horizontally (around the omni), flat vertically 
(ie parallel to the omni), with the omni at the focal point of the 
parabola.  It can even be made out of mesh for lower wind resistance 
as long as the mesh is smaller than, um, a certain size.  By the look 
of the Galaxies around the place an inch or two square is OK.
