Antenna
The flexible 80 cm (about 32 in) marker that sits on the net edge, directly above the sideline, on a regulation FIVB or NCAA net. The ball has to pass inside the two antennae; anything that clips or crosses outside the inner edge is out. It is a simple piece of equipment, and it ends a lot of high-risk line swings when hitters get tight to the pin.
Example
A pin swing catches the right antenna. The up official stops play right away. Point and ball to the defense.
Frequently Asked Questions
What happens if the ball hits the antenna in volleyball?
Play stops. The ball is out, and the team that did not last touch the antenna gets the point. Treat it like any other out-of-bounds contact on the net structure.
