There are three main satellite TV dishes in use by companies that provide different levels of service from about four orbiting satellites. Unlike the TV dinners from years gone by, you do not have to cook these dishes in the oven and they provide more food for thought than anything else.
Which of the satellite TV dishes you use will depend on the type of service you want and the receiver you are using. The most popular Direct TV dish is the 18-inch round that works with a single LNB, Low Noise Blocker receptor, which collects the signal from the parabolic dish, with two outputs, It is commonly used in homes with two television sets, or more, which requires being able to watch two programs at the same time.
The cables from both outlets can be connected to two different receivers so as to be able to record one program while watching a second show, provided your receiver is equipped with a digital video recorder. Other satellite TV dishes you may choose is an 18-inch by 20-inch oblong with three LNBs and four outputs or a 22-inch by 36-inch dish that is used for World Direct Services, usually for Vietnamese, Chinese and Asian programming.
