I've noticed some indoor TV antennas have a dial on them that supposedly fine tunes the reception. Can someone explain how that works and if it's worth the added cost?
My best guess is it's just a potentiometer to enable more exact impedance matching but I don't know if it would be matching the impedance of the output cable and TV or the antenna itself.
