Topic: Better FM antenna thought...
I live out in the country and all of my radios struggle without some sort of antenna augmentation, let alone my little Chumby One...
I looked at a rather terse datasheet for the FM chip, mostly block diagrams:
Pin 7 is RFI and the orgin point of the current antenna, it looks like. Pin 8 is RFI ground, which looks like it traces over to the "normal" ground on the edge of that PCB.
My tentative questions regarding this information are:
- Why not connect a folded dipole of some sort to these two points?
- What would the input impedance need to be to be most effective? How sensitive or flexible is that value?
Disclaimer: I am not an EE by any stretch and I only know a little about AM radio theory, let alone FM, so please tell me why this will not work. :-)
