Satellite TV Dishes Come In Three Flavors
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.
Four Satellites Used for​ Programming Signals
There are four satellites in​ geosynchronous orbit above the​ equator, which is​ why satellite TV dishes must be pointing towards the​ southern sky, at​ different longitudes, for​ different programming options .​
At 95-degrees, the​ satellite is​ used for​ the​ larger dish for​ World Direct Services.
The dual LNB dish only looks at​ the​ 101-degree longitude satellite while the​ three LNB dish will view one of​ the​ others, at​ 110 or​ 119-degrees .​
The triple LNB units are required for​ high definition programming as​ well as​ some local programming capabilities.
To watch more than one television from the​ same satellite TV dishes you can use a​ multiswitch without any loss of​ signal strength .​
The signal from the​ satellite is​ connected to​ the​ switch using RG-6 or​ RG-59 coax, and​ additional cables can them be run to​ the​ different television sets .​
If you have placed your satellite TV dishes away from your home and​ need to​ run cables into the​ house underground, be sure they are encased in​ a​ weatherproof conduit to​ prevent damage from the​ weather .​
Polyvinylchloride pipe (PVC) is​ often used for​ underground wire installation and​ should be sealed properly on either end to​ keep moisture from damaging your coax.
