Satellite technology isn't rocket science . . . well, okay, it's actually not that far off. But, understanding how satellites work to send incredible television programming quality and variety into your home isn't too difficult. Companies like Dish TV and Direct TV have harnessed the amazing signal-transmitting abilities of satellites in order to send a new generation of broadcasting into each subscriber's individual satellite dish.

How Your Satellite Dish Works

In a way, satellite TV isn't too different from traditional broadcasting, which uses a tall antenna to send signals to smaller antennae on people's houses. But those signals are often blocked and distorted by everything from trees to the curvature of the earth. Satellites send the signal down from space, on a path that never has an obstacle.

Your satellite dish is the 'new' TV antenna. It's a bowl-shaped object that, nowadays, isn't any bigger than two feet across, and may be either completely round or slightly oval-shaped. It has a central protrusion in the middle - when the signal hits the dish, it bounces right to this central point, and from there, it travels through the system into the receiver in your home.

An important component of your dish is the low noise blockdown converter, also called the 'LNB'. This filters out the 'noise', or non-programming signals that come into your dish. It's important to remember that this is a sensitive device - treat it with delicacy, and if you wish to paint your dish, avoid painting this part of it.
