What is a transponder in satellite TV?
For satellite, the BBC utilises a number of transponders on a number of satellites. The satellites are arranged in such a way that a correctly- aligned satellite dish will be able to receive signals from all the satellites in that specific arc.
What is a dish TV transponder?

What does a transponder do?
A transponder is a radio transmitter in the cockpit that receives a signal from “secondary” radar and returns a squawk code with the aircraft’s position, its altitude and its call sign. It is constantly being pinged, helping air traffic controllers on the ground determine the airplane’s speed and direction, too.
