Not the food we eat, but I think most of us are familiar with it. It is a bowl shape oval that usually or always (I think!) facing the sky. Actually it is a special kind of antenna that receives signal on a designated broadcast source, in my case mainly FTA (free-to-air). The shape of the dish is parabolic which is designed to reflect the signal to a specific point.
Basically, the Dish purpose is to capture or catch the signal then bounces it to its feedhorn. In the assembly of dish we can see an extended arm that has a tip that is pointing at the dish. I is called the feed horn or LNB (Low Noise Block-downconverter), it is the one responsible in organizing the signal collected by The dish (in this case a radiowave). It then passes the signal onto the receiving equipment (Receiver), then just watch TV (Yes!). Ideal Dish size to be used usually depends on location, there are areas that might need a bigger or smaller size, I guess distance from acertain satellite is the factor.
I think here in the Philippines a 55 to 60 cm long axis dish plate is Ideal in getting signal from Agila 2. Satellite dish size are included in the data produced in satbeam.com, just locate your area and the satellite you are pointing.
Things to check in Satellite dish Installation, I'm not an expert but these are pretty basic:
- After finishing the dish assembly, make sure that nuts and bolts are well tighten.
- Before Mounting it permanently make sure that there is no obstruction between
- After mounting the dish (ex. wall), make sure that it is stable.
- The feedhorn (LNB) should be secured properly, the inside of its assembly should be dry always, check the sealant or add one.
