Antennas
They were called aerials
They are also known by antennas and their job is to receive electromagnetic waves through the air, delivering them to the receptors. They are made of metal and have many shapes,but their purpose is only to work as a bridge between radio and TV stations, and the TV and radio receptors.
The plural of antenna is:antennae, if you're referring to the appendages of an insect;antennas, if you're referring to aerials for picking up radio/tv signals.
No, we need 3 aerials for our next meeting (2nd June) thanks.
Television aerials can be purchased from Argos, Best Buy, Amazon, Currys, PC Advisor, Home Base, Canadian Tire, Walmart, Home Hardware and Home Depot.
You may find digital TV antennae at any retailers that sell TV sets.There are also many sites on line that sell antenna also, this is the best answer I can give on this question. I wish you luck.
Most TV is still transmitted through the atmosphere by transmitter aerials on tall masts.

No - radio telescopes are (to put it simply) giant aerials. They gather radio signals from outer space, bringing them to a focal point. The signals are sent to computers for analysis.
