Query: Didn't work at all

Had hoped that this item with its generally positive reviews would solve my elderly mother-in-law's AM weak reception problem on one particular station that she listens to for hours each day, but it did ABSOLUTELY nothing. ZERO! Already had moved her radio to a more advantageous position in regards to the station's signal. Tried all kinds of positioning, two different high quality radios, and numerous tuning adjustments to no avail. Re-read the directions several times to be sure that I didn't miss anything.
