What is the difference between AM and FM antennas?
AM antenna is used for AM(Amplitude Modulated) wave and FM antenna is used for FM(Frequency Modulated) wave transmission/reception. AM stands for Amplitude Modulation while FM stands for Frequency modulation. Refer basic difference between AM,FM and PM.
Which type of antenna is used in AM and FM transmission?
In AM, a single wavelength is 984 feet for a 1MHz signal. In FM, one wavelength is about 12 feet. Thus, the popular quarter-wave antenna often used for AM might be 246 feet high, and the FM antenna elements would be only around three or six feet long, depending on the antenna design.
Does AM or FM travel further?
FM radio waves also travel horizontally and skyward. However, due to the higher frequency of the carrier waves, the waves that go skyward are not reflected. They pass through the atmosphere and into space. Although AM waves can be received at greater distances than FM waves, FM.
What is the advantage of FM over AM?
The main advantages of FM over AM are: Improved signal to noise ratio (about 25dB) w.r.t. to man made interference. Smaller geographical interference between neighboring stations. Less radiated power.
Why is FM radio reception poor?
Causes of Poor FM Radio Reception Distance: You may be too far from a station transmitter to receive a good signal. If you’re too close to a transmitter, the signal may overpower your radio. Stationary obstacles: Radio signals can be affected by physical obstacles such as hills, buildings, and trees.
Do FM antenna boosters work?
Antenna boosters can’t simply boost the signals broadcasted by the radio stations. It’s actually impossible. They work their wonders by increasing the gain that the antenna picks up.
What are three types of antenna types?
There are several different types of antennas in three broad categories: omni-directional, directional, and semi-directional.
Should an FM antenna be vertical or horizontal?
The antenna for a right hand circularise polarization satellite (NOAA,meteor,etc) should be placed horizontal and with the open part of the dipole pointed towards the south.
What is the principle of antenna?
How does an antenna work? The antenna at the transmitter generates the radio wave. A voltage at the desired frequency is applied to the antenna. The voltage across the antenna elements and the current through them create the electric and magnetic waves, respectively.
Why is DAB radio so bad?
Much worse – because it’s an older CODEC. Internet radio feeds will be using AAC or other more efficient CODECs. The only station which broadcasts on DAB with decent quality is Radio 3, and even that is -just- OK. Generally, assuming you’ve got internet coverage, you’re better off streaming than using DAB.
Who makes a good FM radio?

Is Sangean a good brand?
I own several other Sangean radios and they’re all high quality. They’ve all been very good radios. Sangean is equal in quality to Panasonic and Sony. I definitely recommend this radio over the Tivoli Model One.
