[TowerTalk] Force on a dish?

[Joe Subich, W4TV]

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).

       former Director of Engineering, BAF Communications -  
       we built a large percentage of the broadcast satellite
       trucks.
