Q. What is the size of antenna in volleyball?

Answer

The antenna is a fiberglass or similar material rod that is 1.8 meters long and 10 millimeters in diameter. It's attached to the net on both ends. The antenna has a peak that's 80cm above the net and is striped with contrasting color at that length (often red and white). The 2.55-meter-tall goal posts are set up between 0.5 and 1 meter past the touchlines. The posts have been rounded and are wire-freely planted in the ground. The court's dimensions are 16 meters in length, 8 meters in width, and at least 3 meters in width on all sides. There is a 7-meter free-play zone above the field.
