I need to know how the 2 Radios in our GD379FL get their signal, I know it comes by way of the TV antenna,What I want NEED to know is HOW, Has I replaced the one that came with our unit with an Winegard Rayzar Air Amplified HD Antenna,,At this time I lost 3 of my FM stations, that I had before changing, to the new one. With the new one I get more TV OTA HD stations, Thanks for your help,,,,,
 
I looked into upgrading our TV antenna with the rayzar or one of the other better antennas. Since the FM/AM signals come through the TV antenna I looked at the frequency ranges for the upgraded antennas. They did not receive the FM/AM range of frequencies so upgrading would cause the loss of AM/FM reception, I believe that the rayzar was one of the antennas that didn't receive the AM/FM frequencies. The only option was to upgrade the TV antenna and they add an antenna for the radio.

Hi Nelson & Susan (@PolarBear),

Early models had a splitter behind the booster switch where we ran cable to the second TV and radio. New models have five (5) connectors on the back of the booster plate with a dedicated line to the radio.

Sometimes, what seems like progress really isn't. :(

The FM radio band lies between VHF analog TV channels 6 and 7. So until a few years ago, an antenna designed for the VHF TV frequencies (channels 2-13) would span the FM band as well. The UHF channels (14 and up) were usually received on a separate section of the same antenna, so one antenna would receive VHF TV, FM, and UHF TV.

To implement digital TV transmissions, the FCC decided to migrate all the VHF stations to UHF frequencies. In order not to confuse everyone, the stations could continue to identify as, for example, "Channel 4" (now called the virtual channel number), even though in fact they would really be transmitting on UHF channel 37. See www.tvfool.com for listings of real and virtual channel numbers.

Since UHF signals are generally weaker than VHF, higher gain antennas for UHF are needed. But since VHF antennas would soon not be needed (once the migration was completed), the antenna manufacturers decided to make UHF-only antennas. Unfortunately, reception of the FM band (since its located in the middle of the VHF TV band) was lost as well. When you upgraded to the Rayzar antenna, you probably got an antenna that's optimized for just the digital UHF channels. It will still receive FM signals, just not as well as antenna designed for VHF-TV/FM.
