You need to be more specific. Where is the FM antenna on what? The FM antenna at a radio staion could be on a mountain. FM is called line of site transmission. Meaning, it shoots a beam , or wave, in a staight line to your antenna on your car or house. So, FM can be heard even if you are going through a tunnel, provided there are no mountains to block the signal. It is also called Frequency Modulation. AM is Amplitude Modulation. It is bounced up and down between the atmospere and the ground, until it hits your antenna. So, AM can even be heard if mountains block your signal. It simply bounces over and on top of them to your antenna. Where is your car?
On an AM-FM radio antenna hookup, "f" typically refers to the FM (frequency modulation) antenna connection, while "g" usually denotes the AM (amplitude modulation) antenna connection. The FM antenna is designed to receive higher frequency signals, while the AM antenna is optimized for lower frequencies. Properly connecting the antennas ensures optimal reception for both AM and FM radio broadcasts.
The FM Trap is used to reduce offending FM signals that can cause audio and video interference. Designed to attenuate the entire FM band and Average -26dB. It's a piece of hardware between the antenna and the preamplifier.
check your antenna connections.
There are many online retailers one can buy an FM antenna from. They can be purchased from ebay, Amazon, Best Buy, C. Crane, Winegard and Antennacraft.
Any antenna can receive anything, but not very well unless it's the correct length for the frequency you're trying to receive. Yes, this antenna will work well so you will not need a special FM only antenna.
In the rear glass not In the windshield...
it is built into the back window
i think it does.
The antenna wire being unplugged from the antenna can cause this.
I believe it is the same antenna for the AM in the real window above the heater elements.
i think our head set acted as antenna..
1). If it's getting any FM stations, then the radio is OK.2). If it's getting the strong (nearby) stations but not the weak (far away) ones,then check the car's FM antenna, the connection between the antenna and thecable, the condition of the cable from the antenna to the radio, and the connectionbetween the cable and the radio.
