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 !!!

Well I have just recently had a renewed interest in terrestrial radio in my area (Dallas/Fort Worth). Things were getting pretty bleak there for a while and I had pretty much stopped listening to any FM broadcasts and had Sirius installed in my car. Jagger was taken off the air and replaced by Lex and Terry; 97.1 The Eagle (the only remaining rock station)was replaced by another station playing mexican music.

Now jagger is back on mornings on a dedicated talk station. The first non-commerical country station has popped up 95.3 The range. 97.1 the eagle is back on the air and even the classic rock station 92.5 has changed to a better mixed format of Southern rock/country. We also have a great community radio station 89.3 that has a great variety of formats from blues, reggae, country and many others. Classical 101.1 is a great classical station as well. Now we need a good jazz station and a better oldies station that focuses more on the golden oldies and we would have it all. Next I plan to get an HD radio tuner to check out the available digital stations in my area.

BTW that antenna worked fairly well. I was able to pull in 89.3 clearly which I was not able to do with the little string antenna it came with. I am still unable to pull in 95.3 which is disappointing but it is one of the weakest stations in my area.
Tommyv,Try kntu 88.1 for great jazz.Comes from Denton though.Might need a better fm Antenna.

@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.
