Dmtaurus Posted August 23 Report Share Posted August 23 Have a 2015 Edge SEL with the satellite radio. Satellite radio works great and the FM does too. But the AM reception is fair at best. I see the sail antenna on the roof and was wondering if that IS the AM antenna or is it somewhere else. I looked in a Ford parts catalog and it appears there is a $40 module in line. I am not sure where to begin. Any help is appreciated. Quote Link to comment Share on other sites More sharing options...
edjunior Posted August 24 Report Share Posted August 24 What is this "AM" radio that you are talking about? It seems I have heard mention of it, but it slips the mind. Oh heck, just funnin' with you. I haven't listenet to AM radio in so long, I just don't know much about it anymore. I've had my Edge now for a year, and have never listened to it. I've had my truck since 2019 and I think I turned it on once or twice just to see if it was really there. That being said, I don't think the antenna for AM is in the sail. There's just not enough there to provide any good reception. I suspect it's like a windshield antenna or something similar. Anyway, we'll hang out and see if someone comes along that knows.

garycrist Posted August 24 Report Share Posted August 24 Once they got rid of any thing that resembles an antenna and replaced it with a Ferrite Core, reception has not been the same! Replacing the "Shark Fin" with "Rubber Duck" or anything else, might be detrimental to reception too. The antenna for AM reception, needs to be matched to the radio.

Wubster100 Posted August 24 Report Share Posted August 24 AM/ FM1 Antenna The AM/ FM1 antenna (also called the audio unit antenna) is an on-glass antenna, mounted to the left side of the rear window. It receives AM/ FM radio waves and sends them through the audio unit antenna amplifier to the ACM via the audio unit antenna coaxial cable (also called the AM/ FM1 antenna coaxial cable). AM/ FM1 Antenna Amplifier The AM/ FM1 antenna amplifier (also called the audio unit antenna amplifier) amplifies AM/ FM radio signals to improve reception. The amplified signal is sent through a coaxial cable to the ACM. The amplifier is powered by the ACM through the coaxial cable. Quote Link to comment Share on other sites More sharing options...

Dmtaurus Posted August 24 Author Report Share Posted August 24 To Wubster, is the AM/ FM1 antenna on or near the rear small, left side sail panel glass and behind the big plastic interior wheel-well cover? Can you say where the amplifier is located? My first attempt would be to check the connections for corrosion. 2 Quote Link to comment Share on other sites More sharing options...
Wubster100 Posted August 25 Report Share Posted August 25 @Dmtaurus AM/ FM Radio When the AM/ FM mode is selected, the radio amplifies radio waves sent from the antenna. It then selects the requested frequency, converts and amplifies the content. These fluctuating audio signals are output as AC output voltage to power the speakers or as an input to a separate amplifier. If equipped with a FM2 diversity antenna, FM radio waves are collected and sent to be amplified by the FM2 diversity antenna amplifier. A coaxial antenna cable sends the amplified signal to the ACM. An ACM antenna signal comparator uses both antenna signals to reduce or eliminate FM distortion in poor signal environments. If equipped with HD Radio capability, the radio will automatically detect and playback the improved sound quality and multiple programs of HD broadcasts. AM/ FM1 Antenna The AM/ FM1 antenna (also called the audio unit antenna) is an on-glass antenna, mounted to the left side of the rear window. It receives AM/ FM radio waves and sends them through the audio unit antenna amplifier to the ACM via the audio unit antenna coaxial cable (also called the AM/ FM1 antenna coaxial cable). AM/ FM1 Antenna Amplifier The AM/ FM1 antenna amplifier (also called the audio unit antenna amplifier) amplifies AM/ FM radio signals to improve reception. The amplified signal is sent through a coaxial cable to the ACM. The amplifier is powered by the ACM through the coaxial cable. FM2 Diversity Antenna The FM2 diversity antenna is an on-glass antenna, mounted to the right side of the rear window. The FM2 diversity antenna improves FM reception in urban areas or anywhere large objects reflect FM signals and create multiple FM signal paths. FM2 Diversity Antenna Amplifier The FM2 diversity antenna amplifier amplifies FM radio signals and transmits them through a coaxial cable to the ACM. Voltage for the amplifier is provided by the ACM through the coaxial cable. GPS/Satellite Radio Antenna The GPS/satellite radio antenna contains a GPS antenna circuit board that receives radio waves containing GPS and satellite radio data (vehicles equipped with a satellite radio). The data is sent through the coaxial cable to the APIM ( GPS data) and through a splitter to the ACM (satellite radio data). Cellular Antenna If equipped, the audio unit antenna contains a cellular antenna circuit board that receives radio waves containing cellular data. The data is sent through the cellular antenna coaxial cable to the TCU. TCU Antenna The TCU antenna is used is used to boost reception for incoming and outgoing cellular network data. It is a compact, cellular phone type, planar inverted-F antenna 1 Quote Link to comment Share on other sites More sharing options...

Satellite radio works great and the FM does too. But the AM reception is fair at best. As FM is working great, the circuitry is working, after all it's an AM,FM antenna. So, the best way to improve reception in AM is to drill a 1" hole in your fender and attach a 42" telescopic antenna.... On my 2009, the AM works great. I can receive at a minimum three stations. Maybe four after 9 pm. (Insert sarcastic laugh). Actually, I never listen to AM or FM. Usually only SIRUS XM news and do-wop. Sometimes a CD or DVD, sometimes a talking book ripped to the hard disk. (Borrow them from the local library and rip them to the car.) Edited September 22 by enigma-2 Corect speling 1 Quote Link to comment Share on other sites More sharing options...
