Are satellite dishes redundant?

I'd regard a Sat Dish as an 'Active' antenna and a terrestrial aerial (without an amplifier) as a 'Passive' antenna. With an amp. it's an active one.
Active antennas are becoming more common as using higher transmission frequencies becomes more and more necessary. Think you will find the receiving (patch) antenna in a mobile 'phone is becoming effectively an active antenna.
