Television Tower |

|
||||||
| Television antennas are built on tall towers so that high-frequency signals (which only travel in a straight line) can reach viewers without being blocked by nearby hills or buildings. Small dishes on this tower send and receive microwave signals from other stations or from reporters broadcasting live from nearby locations. | ||||||
