"trouble with all this was i couldnt figure out a way to improve ALL the bands with ONE antenna " You CAN'T... the AM and FM antennas are separate, go in to separate inputs, and to separate parts of the circuitry. If you study the part of the schematic I posted you will see that. One could make an external FM antenna from 300 ohm twin lead. Here is a site with the plan to make one.

Or, you could order one ready made like that and wire it with 2 pins and insert them in holes 1 and 2 of the little socket. Amazon and eBay both carry them. Good luck [url=https://www.kopn.org/about/antenna/][/url]
