I hope someone can help me.

I have a Denon home stereo and I want to add an antenna for FM stations.

The back has an coaxial input for FM.

I made this.

But the reception is not great. It picks up some FM stations, but most of the others only come in in AM.

Rotating antenna does not help much.

Any thing else to try?
