Cheap DIY FM Antenna


I bought a used Sansui TU-217 some months ago just to have some background music in my living room, I have two questions:

1-There are 2 300 ohm and 1 75 ohm taps in the back of the unit, which one should I use ?

2-My current antenna is a piece of wire connected to the 300 ohm tap. I don't receive some station correctly so I would like to build a small antenna. Thing is I don't have space to have a 3 feet piece of wire hanging inside my living room. Also I live in an apartment so putting it in the roof is not an option.

What can I build that's small and serves the purpose ?

Thanks !!!

@acman3. How did you get Kntu 88.1 to come in clean what antenna do you suggest.  
Calvin, actually I only listen while driving, but I drive a lot.😊
I don't even own a tuner at home so I'm worthless on the antenna. Maybe try streaming?

KNTU is a great Jazz station. Whoever does programming is excellent. 
I know. I drive a lot too. The sound quality in McKinney and Denton is great.  Wish I could get the same in Uptown Dallas.
