How do I connect my antenna to my FM radio?
How do I connect my antenna to my FM radio?
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.
What makes a good FM radio antenna?
The overall length for the antenna should be about 150 cms, i.e. each leg should be 75 cms. This length should make the resonant frequency fall slightly in the lower half of the FM broadcast band, but often the more popular stations may be found in this region.
How do you make a 300 ohm dipole antenna?
The usual formula to make a Dipole antenna is to divide the frequency in Mhz into 468 and the result will give you the length of the Dipole,. Then you simply cut it in half and attach one side of your 300 Ohm feed line and then the end of the feed line to one terminal per side of the tuner input.
What is a 75 ohm FM antenna?
There isn’t really such a thing as a “75 ohm antenna.” What happens is actually a bit sneakier. Modern antennas use a device called a balun that serves two purposes. The result is that the 300 ohm impedance is reduced to 75 or 50 ohms which is a much more compatible result for copper coaxial cable.
What is the difference between 50 and 75 ohm cable?
Impedance is how cables are measured. It refers to the amount of resistance compared to the flow of electrical energy. A 50-Ohm cable will provide a better result than a 75-Ohm cable. This means that you will achieve better performance from your installs with a lesser Ohm “number”.
How do you use an AM loop antenna?
For tuning, first dial-in on the radio to the frequency of the station you wish to receive. Then, aim the Loop Antenna in the direction of the radio station. Then tune the dial on the antenna until you hear a signal enhancement. Finally, fine tune the receiver to peak the signal.
How do I get good AM reception?
You can get better AM reception by using an external antenna such as a loop antenna, placing your radio near the window with its rear facing outside, or switching off/moving away any electrical appliances that have been proven to interfere with your radio’s reception.
How do you make an antenna with speaker wire?
How to Make a Loop Antenna for an AM Radio
- Cut the speaker wire into a 20-foot length, using the small wire cutters.
- Leave one end of the wire free.
- Crimp on the 12-gauge spade terminals to the bare wire using the wire crimpers.
- Coil the speaker wire as tightly as possible, creating approximately a 10-inch coil.
How does an AM radio antenna work?
How does an antenna work? The antenna at the transmitter generates the radio wave. The voltage across the antenna elements and the current through them create the electric and magnetic waves, respectively. At the receiver, the electromagnetic wave passing over the antenna induces a small voltage.
