Do you need an antenna for a radio?

Why does a radio need an antenna?
Antennas are required by any radio receiver or transmitter to couple its electrical connection to the electromagnetic field. Radio waves are electromagnetic waves which carry signals through the air (or through space) at the speed of light with almost no transmission loss.
How do I connect my antenna to my stereo?
Connect the antenna wire to the antenna terminals on your stereo. Flat 300-ohm antenna wire attaches directly to screw terminals, and round coaxial cable attaches directly to a cable-style F-connector. If necessary, use an adaptor to go from one type of wire to the other type of connector.
Can I use my TV antenna for FM radio?
Yes. You can quite happily. Although a TV antenna is optimised for high VHF and low UHF frequencies, they are capable of picking up broadcast FM frequencies well enough. It is common to find many TV aerial installations wired to a dual FM/TV faceplate allowing you to plug a flylead into your FM receiver/tuner.
Can I use cable wire for antenna?
How to utilize cable TV wiring for your TV antenna. Yes, you can connect your TV antenna to your cable TV wiring system. If your home is wired for cable TV and you want to cut the cord and drop cable in favor of a TV antenna the same coax cable can be used for the TV antenna. It’s likely a lot easier than you think.
What happens if you transmit without an antenna?
The electrical issue is that reflections from non-resonant aerials need to be coped with. With hand held gear, the power involved is relatively low. In a TV broadcast transmitter, it could be mega high, so even small antenna mismatches can cause pretty substantial reverse power, which can, and does cause damage.

Does my car need the antenna?
Without an antenna, a car radio will not be able to pick up radio stations but will still work with other functions. There are ways to listen to the radio on your car stereo without an antenna, including using an FM transmitter, using your car’s chassis as an antenna, and your smartphone.
Most radios that require an external antenna have an “antenna” and “ground” post terminal at the chassis rear, some may have a couple of wires coming out of the chassis. A good radio working properly may pick up a station or two without an antenna connected but reception will be weak and likely very noisy.
How do you hook up a FM radio to an outdoor antenna?
Loosen the screws on the outdoor antenna’s terminals, attach the antenna wire or coaxial adaptor and re-tighten the screws. Feed the wire into your house through a vent, the soffits or a newly-drilled hole in your wall. If you drill a hole, weatherproof it with caulking. Run the wire to the room containing your stereo or FM radio.
