The best long distance FM antenna ever made was the APS-13 made by Antenna Products Company. It went out of production in the early part of this century. You conceivably could find a used one with want ads in Craig's List, Audiomart, etc. Combine that with a decent rotor (still widely available) and you should be clearly able to pull in your 90 mile station from the attic (unless you have a high mountain inbetween) or unless your attic is less than 20' above the surrounding ground.
