1. Since a player can play a ball over nonplayable area if the player is in playable area, it's not a good idea to blow the ball dead until it contacts non-playable area. You'll get burned someday blowing the whistle too soon.

If you mean antennas, the net is the net all the way, not just antenna to antenna.
