Don't even think about trying to move with a dish in the vertical
position. The broadcast satellite trucks stow their dishes "face
down" on the top of the vehicle. Any other orientation will most
certainly rip the antenna off the mount or flip the vehicle at any
normal travel speed (if it isn't destroyed at the first overpass).

we built a large percentage of the broadcast satellite
