We used to use our cable’s TV signal for FM, I think all FM is between channel 6 and 7, but Cable Companies now deliberately block FM.
I have two Radio Shack TV/FM antennas, one on the chimney for OTA digital TV, aimed at a point I found on the internet, the other inside my attic, for my main system preamp’s FM tuner, aimed at WBGO’s 88.3 antenna at Columbus Circle in NYC, some 30 miles away.
I get great strong FM from both, I use a 2 way splitter to feed the FM of a Yamaha Receiver in my Garage/Shop system from the TV one on the Chimney
something like this, mines a bit bigger, my memory is thinking 80" long, something like that?
