FM Band Separator
This is a discussion on FM Band Separator within the DTV | HDTV Reception and Antenna Discussion forums, part of the Over-the-Air (Antenna TV) category.
I've never had an antenna before but I'd like to get one for TV and FM reception. All of the posts that I have read about separating out FM signals to route to a FM receiver reference the Winegard CA8800 FM Band Separator. However, it appears that this product has been discontinued. So, I have 2 questions.
1) Is there a different product available that will do the same thing at a reasonable price?
2) If not, can I split the signal coming from the antenna routing one line directly to my FM receiver and route the other line from the splitter to a pre-amp with a FM Trap for my TVs? By not separating out the FM signal, is there the potential to do any damage to my receiver?
The Graveyard Shift
FM wont hurt your tv receiver, but passing signals from FM band and below can make your tv system more susceptible to impulse interference.
Ideally you would keep your FM system completely separate from you TV system (using a separate FM band antenna). But in reality they will often mix just fine.

I've done this before, but, never used a separator. The way I did it, was just come off one of the outputs of my splitter, used a coax over to my Amp, then I had to do a 300/75 transformer because I had the old 300ohm FM inputs on my amp. However, I did have the line coming off of a full range Antenna (2-69). I'm not sure if that would make any difference if you used one of the modified range antennas. Now that I think about it, one may have to use a full range Antenna, since FM is between channel 6 and 7, or use a dedicated FM Antenna.

Thanks for all of your input. I ordered the antenna, preamp, and splitters and installed them over the long weekend. The TV reception is great. I haven't hooked up the FM tuner yet, but will let you know how it works.
Thanks again for your help.
What kind of antenna & pre-amp did you get? Is this an outdoor antenna? I use an outdoor antenna (2 antennas to be exact, a VHF only Antennacraft CS600 that's optimized for 2-13 & FM, & Antennas Direct DB8 for UHF). While I don't currently have antenna hooked to my radio, from my experience, I never had any problems with FM stations creating problems with any TV stations. Since most TV stations are now on UHF, the chances are slim. The only time it might be a problem is if you have a TV station broadcasting on channel 6 (RF 6) & have a radio station on 88.1 in your area, then having an FM trap will be necessary. Chicago currently has an analog channel 6 that is low power, but at least in my area of Gary, IN, there are no 88.1 stations. Even so, you probably won't have a problem with using a coax from the same antenna that you're using for TV for your radio. I know I never had any problems. I never even rotated my antenna, despite having FM stations coming from different directions. At least with FM radio, I find that it's usually more forgiving for not having the antenna aligned to the specific station you want (unlike TV, where it usually matters, especially if the signal is weak). If you got a VHF-Hi/UHF antenna (optimized for 7-51), I doubt for analog radio, that it would matter, as I used an antenna that only worked for digital UHF (barely worked for analog VHF), but had no problems using it to get analog FM.
