There's only one:
-- In a receiving dish, the collected and focused electromagnetic energy changes
to electrical energy in the feed, LNA, or LNB at the focus of the dish.
-- In a transmitting dish, the electrical energy of the transmitter changes to electromagnetic
energy, either at the focus of the dish if the transmitter is mounted there, or else at the
end of a hollow waveguide that escorts it to the focus of the dish.

How do you draw a satellite link in a computer schematic?
Graphically you'd draw a stylised satellite (in orbit) and satellite dish (on the ground), with a dashed line between the two. If the dish is both transmitter and receiver, use arrowheads in both directions. If it is a receiver only, arrowheads should point from the satellite to the dish.

To receive a Satellite signal, you need a LNB which is attached to your satellite dish--The LNB and dish is determined by which satellite TV service you have--either Dish Network or DirecTV.

Are Passive reflectors used in both Active and passive Satellite system?
Yes. The most common antenna for satellite systems is the 'Dish'.The dish is a parabolic , passive, reflector.It merely reflects and concentrates the signal to the LNB receiver.Transmission also works this way, bouncing the signal off the dish, to concentrate it in one direction, in a narrow beam.
Why do LNB's have to be mounted close to the satellite dish?
The LNB takes the signal reflected off the dish, sends that signal through the coax cable to the receiver, where the receiver decodes the signal unlocking the channels you subscribe to.
What do satellite dishes do?
