You can use a special antenna switch with DiSEqC commands.

When changing ASTRA 1 to EUTELSAT for example, a DiSEqC command is sent with the 22KHz tone through the antenna cable. The antenna switch will change ASTRA1 to EUTELSAT. The concept of DiSEqC is a protective trademark of EUTELSAT.

Data rate decides the picture quality of digital TV programmes.

Data rate of about 5-6 Mbit/s coincides with the picture quality of a analog TV programme.
