I often saw these in the 70s, when FM stations were more plentiful, in several directions. It was usually an add-on to a TV antenna, often also a JFD or Finco, which made many good ones just like Winegard, Jerrold and Channel Master!I have gotten lucky twice now - scavenging vintage aluminum antennas (new condition) carelessly tossed onto a ferrous pile.
As per usual s-o-p, I tossed it in the truck bed and weighed out. Connecting this antenna with a 300-ohm twin lead, to two different tuners, yielded unbelievably good results when placed on a 10 foot piece of pipe outside my garage. The band below 96 mc was especially good as I could get adjacent stations, i.e 90.3 (powerful) and 90.7(moderate) with no distortion. 90.1 even popped in with minimal noise from 90.3, aka adjacent channel selectivity.
I recently sold 1964 classic consoles from my garage. Both times, I demonstrated the FM reception of the Sylvania and Fisher using the built-in dipole, adequate but not optimal. The Sylvania, also using a 6AQ8 FM and tubes for mpx decoder, was able to be RE-aligned using a clean air signal using this outdoor antenna. Whatever alignment I did after I recapped it on the bench, was all wrong and I never got the neon stereo indicator to light up.
Both buyers lived in good locations, where the console would be on an upper floor level near an outside wall. Not all locations are ideal, so I recommend an outdoor or at least in the highest possible space in an attic, etc.
