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 !!!

You said CHEAP, right? I built this one with a few feet of speaker wire and a few wooden sticks glued together. Slips nicely hidden behind my entertainment unit, though it is directionally sensitive. You can also build one right on a wall by wrapping around nails... read the directions and you'll see what I mean. couple of links to same project - one has an animation that helps you visualize the design.

Gdoodle, excellent sites. Are you using one of those designs? I'd like to try my hand at making one myself. Does the cable connecting to the cubial have to be 300ohm ribbon feeder cable as well?
Cmk - I am using one such home brew antenna - its hanging on a nail behind my large entertainment unit - out of sight. Hooked up to my 70's vintage Kenwood receiver. Better reception than the store bought thing - but we are in the floor of a valley - hard reception on the low power NPR/classical type stations. I did blow $5 on the 300 ohm ribbon cable - not sure it was worth it. radioshack's is stiff and hard to work with - very hard to strip. Next time I would do that part with speaker wire and see if it sounded alright first.
Gdoole, I'm having trouble locating 300ohm cable. Any suggestions? I was told normal speaker red/black wire would do. Around here, we don't have a radio shack...
CMk - I would just build it with speaker wire - the thing about the 300 ohm cable is that the wires are separated by about a half inch - not sure what this does - but you could simulate this by separating but holding them at half inch with duct tape/electrical tape. I have no idea what the spearation or 300 ohm bit is about - it might be totally unnecessary for short runs. I'll bet it will sound fine with speaker wire. I've built this twice - once with a fancy wooden frame made out of dowels and molding - then the super fast way to build a stationary one - just put four nails in the wall and wrap the wire around in the square configuration... You live somewhere that doesn't have a Radio Shack??? Don't tell me you don't have Starbucks either?...
Note that the ant design has two variations depending on which part of the spectrum you are trying to pickup... I went for the smaller college radio/NPR version.
