The Auto Dish Antenna

Surely there needs to be an automation to delight the consumer.

So a display panel which shows the current orientation to help you find the signal of the right satellite by moving the dish antenna manually.

Better still could be auto detect settings with swivellable and automatic orientation with a small box with buttons.

With number of ip services growing there could be alternate arrangements with other partners to augment the content in that case there could be remote controlled through the home control of the dish antenna to tap these communication signals of some other satellites of the partner or sister concerns.

Technology was made to make human intervention a minimum, but how far are we from such a future

I am sure US and Europe can have the same in one month but what about India?
